"San Antonio Rose" is a #swing #instrumental introduced in late 1938 by #BobWillsAndHisTexasPlayboys. Quickly becoming the band's most #popular number, Wills and band members devised lyrics, which were recorded on April 16, 1940, and released on Okeh 5694 in August as "New #SanAntonioRose". Despite having completed a lengthy Hillbilly/Folk chart run in 1939, which culminated at number one, it quickly rose to the top again, in early 1941.
