Skid Row live set details available, see message from Peel Mailing List member Jim. [1] Also thanks to John F of the mailing list for track titles.[2]
Please note that Ken Garner's In Session Tonight (pg. 284) has a Procol Harum concert show broadcast on this date. The same author's The Peel Sessions, the standard reference for this site, gives the date for the Procol Harum concert as 21 June 1970.
Files 1 & 2 contain the Skid Row concert, whereas File 3 contains only most of the Pretty Things setlist.
