Keith Urban a Go Go

I am on record as not caring very much for Keith Urban and usually I just flip channels when his videos come on, but somehow I caught his old hit "But For the Grace Of God" -- and was amazed to note he wrote it along with Jane Wiedlin and Charlotte Caffey of the Go-Go's. How in the world did that threesome get together? And does this mean that Keith is the new Belinda Carlisle?
