The duo Chas and Dave used to sing songs in American accents, but would astonish people as soon as they started to talk, with their London accents. In the end they thought, 'why should we sing in an accent that isn't ours?' so they started singing in their own. Turns out it was a nice gimmick and it got noticed. They got popular and the rest is history. With a few cleverly penned songs to exploit the 'Cockney' accents, they went on to fame and fortune.
