As a former Marsden Rattler, am pretty sure that Bob Davenport got his version of 'I wish they'd do it now' (as per the 1971 LP mentioned earlier) from Scan Tester. I only recall Scan singing this song and the 'Lakes of Coldflynn'- where he got them you might ask Reg Hall or read his book about Scan- 'I never played for many posh dances' (includes an LP but can't lay my hands on it just at the moment. - bloody good song though- it works in the pub bar as well as the folk club- maybe even better?
