Nothing new in this
Among traditional singing circles it was a common courtesy not to sing the songs os certain respected local singers
Both Harry Cox and Sam Larner referred to this practice - Harry Cox described how he didn't sing some songs he had known for a long time until the 'owner' died
Walter Pardon held the opposite view - he was reproached by a local man one for 'giving his songs away' to collectors
He replied, "they're not my songs, they're everybody's - if you don't let others have them they'll die with you"
