I'll mention two whistlers who are maybe not known.

1. Sam Hinton, the folklorist/singer and general Renaissance man from La Jolla California could to what I've never heard anyone else do. He could whistle in two-part harmony! It was incredible. He could whistle thirds in a song and his whistling is featured on the number "I had a bird and the bird pleased me"...........along with great animal sounds...move over Mel Blanc. As if that weren't enough, Sam could also do two parts of a well-known Bach choconne with voice and his whistle. Sam is now in his eighties and is one of the best of the nationally less-known folk singers of our generation. He is from Texas and he was featured years ago on the Major Bowes program as a one-man band. He plays excellent diatonic "straight" harmonica and has a recording of it which is already a classic. His main gig was that of oceanographer, biologist and education consultant for the university system in California.

Also, Bing Crosby was a prodigious whistler as evidenced by his classic recording of Irving Berlin's "White Christmas".
