Alrighty, then... full disclosure:
I've never commented on this in the least, as I thought perhaps my thinking was wrong, as the aware-of-it majority were so fully in favour. Still, I feel that now is the time to offer my full [supported with details] perspective on Leonard's last night[s] on his 2010 Tour, since I was part of the 'melee' on the last night of his 2009 Tour... so this comes from the feelings of a full participant at that time.
It seemed to turn out okay, even fine, even delightful... however, it did not bear repeating, and I squirmed when I read mention of that possibility. Now, we are at virtually the 'same' juncture... the ending of this year's Tour. Only something is even more different now. Now, we have Leonard's comments suggesting that there may not be another one. There are many variables and a major contingency. There are multiple members of Leonard's band and a huge number of his touring company. Leonard has stated that he won't go on tour again unless he is backed by this very same band; I've no idea whether this extends to his crew, as well. However, with such a large number in his band and an unknown date for a new tour, but contingent on the release of his new album, as well [with definitely no date on that], all of these people need to continue to live their lives and earn income. So, who knows who will even still be available at that unknown date in the future, which cannot even be planned around with any future employment or gigs... "Well, I need to be free for release when/ever Leonard is available for touring, again" ~ hmmm, doesn't wash too well with future 'employers.'
All of that is to say that this may, IN FACT, be Leonard's last night on tour. Leonard deserves only the very best for closure on this night. Sheer elegance.
This relates at this moment to my sharing my feelings at the time regarding our blouse throwing [again, I was a participant] in San Jose on the last night of Leonard's 2009 tour. Of course, we didn't know if it would be his last night of touring, as it could always end at ANY time.
When I first was made aware of the idea, my thoughts [which I recall sharing with only one person] were that "This is either an incredibly tacky or incredibly cool idea... and the jury was still out with me on which. I felt apprehensive about it and did not rush out to buy a blouse, though when I finally did, after seeing the wide, private support for it, I bought several, in case others wanted to join in, but lacked a blouse to do so.
The moment came, we flung them as best we could [though I had to hand mine forward for that, due to my seat location]. It clearly took Leonard by surprize and the band smiled. It seemed to turn out okay and it brought joy and laughter around the world, as people read about it and saw it on video. My feelings remained ambivalent.
I thought, "Okay ~ a ONE-TIME-ONLY happening, please" ~ I feared that if it reoccurred anywhere in the world, we might see "Closing Time" omitted from the setlist and future audiences would miss out on hearing in person an unusual and delightful song of Leonard's.
My reasons for that concern [which are again resurfacing] is that Leonard is the Master of Precision and Perfection. His words, his movements, his clothing, his singing, his music, his STAGE with its Oriental rugs and exquisite beauty ~ and every one of those factors for his band, as well. Does he really want his regal, elegant, and beautiful stage effectively 'cluttered' with anything he didn't deem to have placed there on his own? Our actions certainly were a GRAPHIC demonstration of our love for his work, but was it the best and the most appropriate for him? My ultimate [undisclosed] feeling was that it really wasn't. Cotton and maybe even polyester

everywhere... 'funny,' yes... one time... Done.
Now, however, we are looking at very possibly Leonard's LAST night for our seeing him and his band onstage... and the thought of throwing ANYTHING onstage feels terribly inappropriate to me. It's startling and there are risks to the people, to Leonard's hat on his head, to hats worn by others, to the faces and the instruments there... And the simple regality of Leonard's persona, so carefully wrought across time with serious and fitting intention. Do we really want to see anyone hit by something... or worse yet, shielding themselves from that? Leonard has a wonderful, delightful sense of humour that has shone through many times, but why challenge it on his last night?
My vote ~ regardless of who it is that comes forth with some seemingly great idea for throwing anything ~ is that we allow Leonard's memory of that night to be unfettered, uncluttered, unmarred, by anything that the collective or individualized 'we' think would be fun. He deserves the grandeur of a Shakespearean play or Grand Opera. My vote is to let it simply be that he leaves his stage with our overwhelming appreciation and love. My feeling is that that is enough for Leonard. It reminds me of his interview with Philip Glass regarding Philip's production of Book of Longing. The concept of "enough" and needing just to have enough, and how does one know when "enough is enough" and Leonard's response was to the effect of "... when it's enough."
Okay. There I've said it. Full disclosure, with no disrespect for anything that has preceded that night, but for extra careful, conservative concern for a truly beautiful and elegant ending to a truly beautiful and elegant tour.
As for me [unlike at Red Rocks when I danced

for a bit to Closing Time ], I will be staying in my seat, except for standing ovations.
