Wednesday Night Ride shows lasted 2 hours and were usually presented in the first hour by Peel and the second by another presenter. In this case the show seems to be presented solely by Peel, according to the PasB. The last hour of the show is dominated by Jazz and easy listening, not the kind of music Peel would emphasise so much - unless the PasB forgot to mention the other DJ or he had to take over the whole 2 hour show of Night Ride and play the other DJ's playlist, because of an absentee.
However, BBC Genome  lists two presenters: "The world of words and music explored by John Peel and Jon Curle", with John Muir as producer of the entire two-hour show.
The jazz orientation of the second hour (along with a couple of folk songs by Paul Clayton and Jean Ritchie) may reflect Muir's tastes, starting with the Kenny Burrell track. At least three of the tracks from the second hour are from non-needletime film soundtrack albums - as was common on Night Ride. Although not all the material would appeal to Peel, it's still an adventurous playlist for what was supposed to be an easy-listening late-night show.
Peel has Kenny Everett as guest. There are no recordings of this programme to suggest why he was a guest on the programme or what they talked about.
Unusually or perhaps not, Peel plays most of the sessions and poetry at the beginning of the programme. Guest poet George Macbeth was also a BBC radio producer and one of Peel's supporters at the Corporation (see the Night Ride and Night Ride Poets pages for more details).
↑Stefan Grossman played on Light Of Day, the sole album by Pat Kilroy (1944-1967). It was released in the UK on Elektra in summer 1967, but attracted little attention at the time - apparently, one of the few Elektra LPs of the era Peel didn't feature on his shows.
↑The PasB mentions a Maxwell Williams directing Innomine Players with Canzona a 4 (G. Gabrielle) Consort Of Vicls(?). The In Nomine Players (who have albums listed on Discogs, but not this one) and Consort of Viols, and the composer Gabrieli would be more accurate spellings. The Canzona (Canzone?) a 4 were composed in 1608, says Wikipedia's article on Gabrieli.
