Alternative Comedy Memorial Society (Acms) on Monday May 11th

Minimum one host.

Umpteen guests. 7:30pm start.

Permitted heckles.

Varying price structure.

Much comedy★★★.

Some failure.

NO JERKS.

All taking place in The Phoenix (by Oxford Circus tube), 37 Cavendish Square, W1G 0PP.Thom Tuck (fruity, befuddled and increasingly melancholy The Guardian).Either pay full price (£10), get an £8 ticket (it's just Slightly Cheaper! no audience participation involved!) or go for a £5 'Say The Unsayable' ticket, in honour of our new Permitted Heckle.

Much will be asked of you, if you go for the latter option.★★★ It's a celebration of inventive comedy that's become a cult, with its overstuffed bills, permitted heckles and you-had-to-be-there moments that would never work in a conventional comedy club. (Chortle)
