That would be, respectively, July 14th and any/some/all of the following dates:
2/16
2/17 (both as a four-piece, no Alan)
3/9
3/23
3/30 (all w/David)
I would cast considerable doubt on what Tamblyn said about only one playing an instrument as there's a pic from early March showing all bar Mike playing the usual.
I think someone (forget who, might have been Ian) actually corroborated that they did a few early gigs unplugged, and he had those shows pegged as one of the February ones. I'm vague on the deets but I remember this because I, too, was doubtful of Larry's recollection until someone else stepped in and said it tracked their knowledge, which was much deeper than mine...which is why I brought it up.
The actual thread is buried here somewhere, we can go dig it up if it's important.
