Well, OpenG, I just took a look at this [
www.pbs.org]# sample here.
You can't really see anybody else clearly than Jake and the drummer, Fred Eltringham.
But as Fred is the drummer, and not Mario Calire, this show must be pretty recent.
After they recorded their before-last album "Red Letter Days" with guests and studio guys on guitar (honorable mention: Val McCallum and Mike McCready), they toured it with a guy called Yogi or Yoggie on guitar, whose surname has slipped from my memory. After that, they toured some more, but replaced Yogi with producer Brendan O'Brien, so they could warm up for the recording sessions to "Rebel Sweetheart", their current album.
I don't know if they have another new guy on board now, but you might want to ask here [
www.thewallflowers.com] maybe someone knows.
Bye
Bill
