Ella Fitzgerald - I've Got A Crush On You (Original Stereo) "I've Got A Crush On You" was composed by George and Ira Gershwin first for the 1928 musical "Treasure Girl" and then re-used in 1930 for "Strike Up The Band". Ira Gershwin assisted orchestra conductor Nelson Riddle with the original charts for the song in this recording from 1959. After Ella completed her "George and Ira Gershwin Songbook", Ira commented, "I didn't realize how great some of this music was until I heard her sing it".
