Lyrics Gus Kahn, music by Isham Jones, 1924 so PD. In G for men, in B flat for women and mixed. I have a phot of my folks and friends in the 30's in an open convertible with a big placard that says "Isham Jones." so he must have been famous and popular into the 1930's. Never forget that picture. Simple, elegant song. Wish I'd written that one.
