[Dixielandjazz] Need lead sheet - "Who Are You?"

Dear John and Beth,
I would suggest that the friend may be looking for the (Worth - Cowan) song recorded by Ella Fitzgerald (1941), the  (Smith-Eager) one recorded by Erskine Hawkins (1949) or the (Rodgers - Hart) composition featured by Peggy Lee (1977).
There is also the following:
"Who Are You?" - Composer: Johann Strauss, Jr., Robert Craig Wright, and George Forrest from the 1972 film 'The Great Waltz'. 
Very kind regards,
Bill.
