Back in 1958, at the New Lost City Rambler's first NY concert, we were peddling a tape (this was pre-cassette) OF "Tom Tunes in Hi-Fi"---45 minutes recorded from older Tom Paley Concerts.

And, IMO, the best tuning comment ever was from Robin Huw Bowen who, when asked how long it takes to tune a triple harp, responded "Nobody knows".
