Jim,

Please don't take umbrage and please stay here. If idiots say idiotic things, treat those with the contempt they deserve.

Bert's singing voice was unusual, and I have occasionally heard faint echoes of it when someone else sings a song that they presumably learnt from his singing. It can sometimes be hard to suppress any trace of how one has heard a song sung -- and of course some singers don't even try. And then again some songs more or less demand at least some of the style in which they have been sung before, for example Irish ones where one instinctively applies more decoration.

Anyway back to Bert. Great voice, certainly not. Great singer, yes, because he knew how to put a song across.
