You have to be joking Vic (even if it was material)
Ewan and Peg kept head above water with occasional tours - apart from First Time Ever which came late in life and was a total surprise, the royalties they got from songs was minimal
After Ewan died Peggy gave me a tape of 'First Time' recorded by 'pop names' - they had receive payment for less than half of them
Tey didn't write songs to make money - most of which made zilch
Immaterial - the songs appeal to different people for different reasons
