I caught up with the documentary on iPlayer last night. Re. Dave not burying the hatchet, that programme was a few years old, and since then he played with Rog on his latest Wall tour, apparently just for the hell of it, so who knows?
I saw them at the Syd Barrett memorial/celebration at the Barbican a few years ago, with various acts performing their faviourite Syd song. Rog did a solo acoustic version of one of his own songs in the first half. When the post-Rog Floyd came out in the second half, someone shouted for Rog and Dave made a dry remark like "Yes, I heard he was here earlier". The grand finale was all of the acts on stage together - except Rog. Oh well.
