Strengthened the tradition? No he didn't, Cap'n, he weakened it. Because of his deceit we don't know what song is genuinely 'traditional' and what is a Lloyd creation. I'm now wondering about his version of Creeping Jane - it's a very different melody than the one recorded by Joseph Taylor and has more verses. This latter point seems to be very much a Bert Lloyd trait - create the verses that the people should have sung but carelessly forgot to do so. A couple of years ago I heard Martin Simpson wryly explaining the origins of Peggy and the Soldier, telling us that Bert 'came up with' some extra verses.
