Beyonce is a joke!
Have you ever seen her encounter with PETA? BOOM Bitches!

Glastonbury:
U2- Epic
ColdPlay- Epic
Jesse J will be there
Cee Lo Green: will be there, his music fit the scene
Jimmy Cliff
Janelle Monae

What will Bey sing? Single Ladies? Get me Bodied? Halo?

She has no place there, and she is performing last.... We'll see how she fares with the crowd cause when J was there he was not excepted by most, rappers are not musicians, and Beyonce is NOT a musician, so she will dance? GTFOH. Real musical performers will be there, what will she play? Her hair? Only in the states do people except this type of artist. Really is a shame.
