Trying to figure Bing Crosby

He was not tall, nor athletic. He was not bad looking, but with those ears certainly not dashingly handsome. (And, of course, there was that famous pot belly.) He had a smooth style, but it had enough of a dash of the corny that it did not rate with many of the great screen lovers. He was no challenge to Adolph Menjou as a stylish dresser. He was an awkward kisser and dancer on the screen. Yet he ranks as one of the great heart-throbs of all time. Go figure. I guess it must have been that voice, reckon?
