After splitting in 1982, original Jam members Rick Buckler (drums) and Bruce Foxton (bass guitar) are to reform for a series of "intimate" gigs followed by the release of a new album. Paul Weller (lead singer, guitarist & song writer), who has had a successful post-Jam career with The Style Council and as a solo artist won't be joining them.
This is a bit like restaging Hamlet without the prince. Weller was the driving force of the band, without him The Jam isn't really The Jam. I believe that Weller regards such reunions as a "sad" exercise in nostalgia and I think he's right. See here for a news report. Do you welcome this reunion? Who would you like to see reform, or not?
