Which group or artist - T - recorded or performed Rudolph The Red Nosed Reindeer. I thought that Gene Autry (the singing cowboy) had the hit, all those years ago, in 1948, but, in this case the Quizmaster is obviously looking for another one of the 70 to 80 performers or recordings. I confess to being baffled.
Thank you for an exceptionally quick answer, but it does not fit the criteria. The answer is a group or performer with one name only, beginning with T .
