The bassist does, he also produced his last record (and has done the forthcoming Autre Monde record which I hope will be very good as I saw them play a bunch of new songs recently and was impressed.) AFAIK the 2 guitarists from Paddy's current band play in postcard versions and Badhands, the violinist is Dowry who I think is very good, the drummer, I dunno.
Girl Band guitarist does The Claque which is great.Do some of them occasionally play with Paddy Hanna?
Then the bass and drums play with Paddy Hannah, bass sometimes played by the drummer's brother.
I could say more but would have to kill me.
