That's Life is a popular tune written by Dean Kay and Kelly Gordon and first recorded in 1963 by Marion Montgomery for Capitol, in the traditional pop style. The song carries an uplifting message about sticking with life through its ups and downs and moving back on top. The most famous version is Frank Sinatra’s 1966 recording on the album That’s Life, produced by Jimmy Bowen with an Ernie Freeman arrangement, which became a top four hit on the US Billboard Hot 100 and topped the Easy Listening chart. Since then the song has been covered by many artists including Aretha Franklin, James Brown, Van Morrison, Lady Gaga, and David Lee Roth, and it has appeared in films such as A Bronx Tale (1993) and Joker (2019) as well as the video game Tony Hawk’s Underground 2. The tune remains associated with Sinatra and with the idea of resilience and comeback.
