Hold you hard about the film...Isla Cameron was the Folk Song advisor AND sang "The Bold Grenadier" while the rain washed the cross off the grave...but (as Isla had a very scottish accent)..I'll bet a shilling (!!) that Julie Christie really did sing Bushes and Briars...I actually remember Isla Cameron singing on a TV programme (wish I could remember the programme) with Syd Carter and a pubescant Martin Carty
