(Pete the Pick: I can confirm recording date was 1973-03-29, which was a Thursday, the usual recording day for In Concerts. The date of 1973-04-01 is erroneously quoted in the Five Guys Walk Into A Bar... boxset, but that day would have been on a Sunday. Trust my diary!)
The above mentioned Five Guys Walk Into A Bar includes four tracks from tonight: "You're My Girl (I Don't Wanna Discuss It)", "Miss Judy's Farm", "Angel" and "The Stealer"
In addition to the above, once when flying back to the UK on a BA flight, in about 2008, the audio entertainment available included a BBC Faces concert in its entirety, and I'm fairly certain this is the one: it certainly included "You're My Girl (I Don't Wanna Discuss It)", so the whole concert must be available somewhere
Faces concert. Recorded 1973-04-01 (some sources give 1973-03-29), Paris Theatre. Repeated 26 December 1977.
