Whilst on stewarding duty an agitated Tom Lewis bemoaned about the guy on stage not singing a Stan Rogers song correctly.
Tom should know, says I to meself
however they offender was giving a workshop next day on Stan Rogers songs (more reason for Tom's displeasure)
I declined the w/s as a result however at a later stage the "offender" was telling us he had read the lyrics and listened carefully to Stan's records and they were not consistent
as our "alleged" offender said - "which side of which fence do you sit?"
trad (anon) songs have no definitive versions and the folk process goes on
even my own songs have evolved in my time, particularly the ones (most of 'em) only I sing!
