Living: Stevie Wonder is the only one I can think of who would be worth “silly money”. And Kate Bush.
Dead: Bowie and James Brown (With Bootsy Collins) would each be an amazing experience.
Other than that, I just don’t think there are many others I’d really be that desperate to see. Does that make me terminally 1980s?
PS Seen Queen a few times – they were great. Radiohead not so much – more fun to sit at home and listen to the music rather than be at the gig.
