OK, I finally got it figured, I've tried three times to load this and it's been intermittent, I thought it was the Podbean problem but actually I think it was because I ran the mp3 cut through Sound System to clean it up and it somehow deformed the format, so I recorded a fresh copy with Wiretap and it's working fine; back to where we started:
Somebody mentioned Quicksilver here recently, one of my favorite groups from one of my favorite eras. I have this piece that I'd like to share with you sitting in my iTunes file, it's 'Calvary' by Quicksilver Messenger Service from the 'Happy Trails' album. I should have posted it in the recent RR 'religion' topic but I wasn't thinking straight. I think it's an absolute classic of the SF psychedelic period, definitely headphones music. For me it was almost life-changing, it brought me into contact with Quicksilver and we discussed making a film together, fortunately I instead took another option which in retrospect was a very smart thing to have done. Quicksilver broke up shortly thereafter.
