I'm sorry !
Ok, I was wrong, it's not augmented. I was singing it to myself in my head and I was sure it was an augmented chord. It isn't. I've gone back to my old notes from when I wrote it down off the record and it's actually a diminished 7th (three minor 3rds).
I haven't got The Portland Collection with me now, but when I have, and Mudcat's working, I'll post the chords from that.
