*groan at terrible gag*
If Sherwood's MySpace is anything to go by then it would appear as though they are indeed Official support for Zebrahead's upcoming UK tour from June 2nd in Cardiff right up until June 12th in Peterborough.
Sherwood are an indie/pop/rock band from California and if you're new to them I'd recommend checking out their MySpace for music samples, music videos, tour diarys and other cool media. Watch this space for any additional support band news on the new tour. Not long now!
