Hmmmm Cab Calloway eh? If the dates that Ted gives are accurate that makes 64 years! That trumps everyone else mentioned. Remember, I'm talking about having a SIZABLE audience from beginning to end.

Anyone else who may have started as early as 1930 and gone on as long as '94?

I guess George Burns is right up there, but I doubt if he commanded much of an audience in his first few years in vaudeville (before he met gracie)....I may be wrong though.
