there's info about The Reivers on Tobar an Dulchuis (which I may not have spelled correctly! Try Kist o' Riches - - -- )

Seems Norman formed the group for a tv programme - perhaps from his school Ballads Club? or from a Glasgo folk club? -- guess I should have read it more carefully - - anyway the original group was:
Josh MacRae   Enoch Kent    Rena Swankie Mona Flannigan

line-up may have changed later on?
