OK, here's my fantasy festival, and one I've chosen to base in the real world, although it might have to be a co-headliner...
10.30 - midnight... NMA
9.15 - 10.15... Sisters Of Mercy
8.00 - 9.00... Carter USM (yeah, they're not splitting up really and announce it here...

)
7.00 - 7.45... The Levellers
6.00 - 6.45 - The Wonder Stuff
5.00 - 5.45... The Justice Tonight Band (look 'em up...

4.00 - 4.45... Inspiral Carpets (would have been higher if Tom H was still the singer...)
3.00 - 3.45... David R Black
2.00 - 2.45... Junker (never heard of them..? OK, fair enough, its my mates unsigned band

) )
1.00 - 1.45... JS and Friends...
EDIT - dammit, jackroadkill mentioned Therapy! They'd have fitted right in with my fantasy festival!!!
