no,Mary,Jims phrase was the ejits that pop their mouths[andwhat WalterPardon would have made of it].it never happened to Walter Pardon,never has it happened in my experience to any traditional singer.
I repeat traditional singers have been shown great respect by the revival.Mary/Jim please give examples of this disrespect[popping of the mouth] to source singers.
CyrilPoacher and his friends clearly had a more relaaxed attitude with their hold the wheel cries,however there is no evidence to suggest anyone popped their mouth at Cyril Poacher in the Blaxhall Ship.
