I am happy to discuss his creativity, I think he was indebted to Peggy, for her excellent musicianship.
I think his ability as a song writer was partly due to his training as a playwright, but he also had a respect for the creative abilities of working people be they fishermen, farm labourers or manual labourers building motorways, he listened to WHAT THEY SAID and carefully studied their speech rythyms and with producer Charles Parker allowed them to speak for themselves in the radio ballads, imo this helped towards the success of the radio ballads.
He was a very professional and polished performer. WHO REALLY SHOULD ACT AS A MODEL FOR MANY PERFORMERS.
