The Boswell Sisters chalked up 20 hits during the 1930s, including the number-one record "The Object of My Affection" (1935). (Of special note is their involvement in a handful of 12" medley/concert recordings made by Red Nichols, Victor Young and Don Redman and their 1934 recording of "Darktown Strutters' Ball", which was issued only in Australia.) They also completed two successful tours of Europe, appeared on the inaugural television broadcast of CBS, and performed on "Hello, Europe", the first internationally broadcast radio program.
