I see Chris, Debbie, and Clem. Who are the other 3 guys? What happened to Jimmy? Frank?

I haven't kept up with the personnel changes over the years. I know Nigel has been out of the band since the early 80's but the last I knew was that Jimmy Destri was still in it. But this knowledge goes back probably 10 years when they had their late 90's (?) sorta comeback.
