Saw this today in an Oxfam Store. The band were called Decameron. The album was called Tomorrow's Pantomime and it was their fourth LP, released in 1976. Obviously it caught my eye enough to note the names and research them online. I've never heard of them or anything by them so I'm not sure it they are my cup of tea or not but I do like the use of the Journey to the Far Side of the Sun / Doppelganger helmet. This has popped up in some obscure places over the years but this has to be one of my favourites...and one of the last.
