Dunno if this counts, but i went to see Sir Spamalot last week for my birthday.
I was actually a little worried cos i have a habit of getting bored after the first act and spending all of Act II wishing they'd stop drawing it out, get to the point and get the singing over with, but Spamalot actually went really quickly, in fact i wanted it to go on longer, even if they just repeated Act I again.
I mean yeah, it was a little weak in places (finding the grail particularly

), but it was still funny and the songs were cool, plus it had Charlie the psycho... plumber? builder? from Emmerdale playing a gay knight who was rather good at crotch thrusting in a thong... i never watch Emmerdale so dunno who he is myself

but apparently the fact it was him was supposed to be pretty exciting.
