We have:

Aaron Crow- Illusionist/Magician/Extremist
Band Of Voices- Singers
Bosom Buddies- Drag Singers
Youth Creation- Dance Group
Martin Healey.- Dances with a broom
Arisxanda Libantino- Singer
Richard and Adam- Opera Duo
Philip Green- Impressionist
J-Unity- Singers

I think Simon will buzz Martin, Amanda or Alesha might aswell.
Simon might also buzz Bosom Buddies
Somebody may buzz Aaron depending on how well he does.

I guess
Simon will buzz twice
Amanda will buzz once
Alesha will buzz no times or once
David won't buzz

Unless dancing with a broom disguised as a nun has become a new art form, Martyn will defo be buzzed.

Also agree that Simon could potentially buzz Bosom Buddies.

I think Simon will buzz Martyn, Aaron and possibly Bosom Buddies
Amanda will buzz Martyn and Araron
Alesha may possibly buzz Martyn
I don't expect David to buzz

Someone should buzz Amanda and Alesha

Will David buzz in the semi finals at all this year- he didn't last year!

I didn't know Martin Healy was on the list.

So far definite cannon fodder, Martin Healy, Thingy Bounce and Meat Diva.

Trying to recall the times David buzzes at all. He doesn't seem to be much of a buzzer full stop really does he? (please correct me if I'm wrong)
