In reply to Misha:
I went to see Allegria last year and I am going to see Quidam in April in Glasgow.
Both great shows, I would recommend to anyone and not just because it's amazing what some of these people can do, but because the whole production effort is fantastic, from the slightly dark storyline that hovers just below the visuals to the music and the costumes and everything.
the tour ends mid-April so if you want to go you had better get a move on. This is supposed to be the last time Quidam is touring too (although that has been said before) so don't miss it if you want to go!
