The 'rights' to the first album - entitled just Five Hand Reel - were transferred to TDB (the dreaded Bulmer) when he bought Rubber Records. The next 2 - Bonnie Earl 'o Moray and For a'that were owned by RCA - and I think these are the 2 that are in dispute. RCA is now part of the SonyBMG empire.
The last album - A bunch of Fives - was/is owned by Topic.

Have I missed one?

The best band of that genre in their heyday, but never really got the recognition they deserved.
