Young Irving Berlin made one commercial recording singing his own OH HOW THAT GERMAN COULD LOVE in 1910 - not too long after his stint as a Chinatown Singing Waiter came to an end! Many songwriters in the 1900-30s were pianists AND vocalists - this episode of American Grooves brings you recordings of composers doing their own thing - GEORGE GERSHWIN, CLARENCE WILLIAMS, JAMES P. JOHNSON, HOAGY CARMICHAEL, WILLARD ROBISON and young HAROLD ARLEN are presented  in pre-1935 recordings - writing it, singing it and playing it!
