I too would be intrigued.
I saw Mk 1 at Rochester Castle in 1972, shortly before the split. The Hartley Morris Men performed Queen's Delight to the tune Princess Royal (which was the only morris tune ACB specifically worked up) oblivious to the odd bar structure! Also on the bill was Harvey Andrews and the JSD Band.

To my knowledge, only three tracks survive: Lord Bateman from Steve Ashley's first album, The Four-Hand Reel and Seventeen Come Sunday from a couple of John Peel sessions which are now on Ashley Hutchings's 'The Guv'nor' series. There are a few tracks on Royston & Heather Wood's album that sound Albion-esque.

Mk 2 comprised Richard & Linda Thompson with Sue Draheim on fiddle, with Dave Mattacks on drums, and Tyger himself, possibly Simon Nicol.
Most of the material from that line up came from Richard's first album 'Henry the Human Fly'.
