Hmm. I don't agree. But
everything is not a BBS, so I'll phrase it in the form of a
writeup.
Son of John Lennon, he has one album, "Into the Sun." One of the sweetest albums I've ever heard; it is all about how much he loves his girlfriend, Yuka Honda (of Cibo Matto). It's a great album, though I've heard people don't like his voice. I don't think it's that bad...Then again, I think Bob Dylan has a great voice....
Sean Lennon can also be found on Butter 08, a side project of Cibo Matto and some other people, and touring with Cibo Matto (he plays guitar or bass or something).
