Thanks, folks!
Yeah, I was lucky to find Dave (the bassist), who's also a swell guy.
He was the only guy to my Craigslist ad: "Upright player wanted for ukulele shenanigans."
He showed up and read down Brandi (You're a Fine Girl) in a few minutes.
That was, incredibly to me, four years ago. This was recorded within like 30 minutes of meeting.
