Just to clarify the above, this is what we know about the 'unidentified shows': The first 'unidentified show' is 100% the same show (albeit incomplete) as the audience recording / bootleg listed as Santa Monica 19 March 72. (the location can't be totally verified but no particular reason to doubt it) Support on the Santa Monica bill was The Blues Project & Fairport Convention. (Is it likely there would have been 2 shows in one day with a 3 act bill? Anyone remember?) Fripp introduces the show "thank you for being patient for two years" (on the audience recording) , and at the end says "maybe we'll see you in two years time" so there's no reason to infer that the second comment might imply it's the last night of the tour (as in the booklet). In the audience recording there are technical problems delaying the start of the show. In the second 'unidentified show' Boz refers to technical trouble in the 'first half'. (Could this mean it's a second show from the same date? It's worth noting that many shows of this era featured technical problems usually caused by mellotrons). I realise some people are less interested in this sort of thing than others. Any thoughts?
