I'd say Young Criminals' Starvation League (the album with the Smiths' cover) or reaching back further, Bare Jr's Boo-tay (though he typically never plays anything off that one live anymore). Third favorite is the newest album.
Bobby Bare Jr likes Dr. Dog. He was singing along giddily a couple of years ago watching them as they opened for him at Iota. Any my wife liked them quite a bit. Me, not so much, though I didn't think they were completely horrible.
