I was there last night (3/12/11) at the Secc in Glasgow.
The Glowbands do still flash initially when you leave, but then are turned off.
They dont flash to any beat as posted by Nikola. As the bands were only activated for certain songs.
The bands are free and you can take them home for a "keepsake" which is good.
I have no clue if the band can now be activated by myself in anyway. Would be good though.
Heres a photo of mine...
