Norfolk were Les Russell, Dick Walinck and Billy Cranston. Joy
Greig (mistakenly Griegs on the sleeve) was a friend of the group and occasionally got up to sing with them on stage. She was asked to sing a few tracks on the LP. Before Norfolk, Joy sang with Linda Wyman under the the name The Joylins, performing around Scotland between 1972 and 1976. She also sang with a group called Buzzard.
Norfolk seem to have been active in Edinburgh, probably in the 1970s (their LP came out in 1979), and were active on Edinburgh's Amber Mile - Royal Terrace, where a number of small hotels held folk nights each weekend.
Billy Cranston was active in Edinburgh in the duo
Broadside (with George Fenning) and in the group Homebrew (with George
Fenning and Johnny Cunningham, later of Silly Wizard fame). Later he moved to Holland, where he lived with his Dutch wife and their daughter. They were friendly with Davey Steele. Billy died in a car accident in Holland in 1984. In his memory his widow ran a folk festival in Holland.
Dick Walinck (bass) became active in the jazz scene, playing with The East End Jazz Band for ten years. He had a reacquaintance with folk with stints in Callanish and Drombeg. Now he's back playing trad jazz in The West End Jazz Band, who grace the Burgh Halls in Linlithgow twice a month.
