Well, I'll be there for one of them - Sparks are one of my favourite bands and the first 'pop' group I got into on my own in the early 70s :-) I know chunks of their songs word for word. I hope they get to play Glastonbury at some point.
Howard - be careful. It's not a full band tour, it's "Four hands one mouth" and features the Mael borthers all right, but just the Mael brothers, doing reworkings of their songs. Reviews of their recent London show were very favourable.
I'll be at the HMV Picturehouse in Embra no matter what. A much under rated band indeed.
