Dweezil Zappa is taking his Zappa Plays Zappa extravaganza on the road in June and July and including a week's worth of gigs in the UK. I'll be going to the one at Cambridge on 21 July. They are also playing in Brighton, London, Liverpool, Glagow, Wolverhampton, and Gateshead. See zappaplayszappa.com.
Dweezil and family have come in for some criticism for trying, unsuccessfully, to force other 'non-official' tribute bands out of business by deploying lawyers and so forth. So there's nothing for it but to get out there on the road and play yer socks off, Dweez!
