Neil,
There are three separate versions that I know of:
(a) the Tol & Tol recording itself (which was issued on a limited edition CD with the
backing track as a bonus item on the disc),
(b) The Local Heroes version (it's possible that a BT version of that recording was issued, but I'm not aware of it), and
(c) a version by Dave Robinson, which appears to be closely based on the Tol & Tol version (this is available on a BT CD from the Pastmasters site).
See the CD "Lead 6" at
http://www.pastmastersmusic.co.uk/CD%27s.htm (for the third one).
Hope this helps,
JN
