"Happy Days" is a song written by Norman Gimbel and Charles Fox. It is the theme of the 1970s television series Happy Days.[3] It can be heard during the TV show's opening and closing credits as it runs in perpetual rerun syndication. "Happy Days" was first recorded in 1974 by Jim Haas with a group of other session singers for the first two seasons.[4] These versions were used only during the closing credits of Seasons 1 and 2, with an updated take on "Rock Around the Clock" by Bill Haley and His Comets used as the opening theme. "Happy Days" was re-recorded by Pratt & McClain at ABC Recording Studios in Los Angeles in December 1975[5] with different lyrics for both the opening and closing credits for Seasons 3 through 10, with the duo including the song on their 1976 album Pratt & McClain Featuring Happy Days and releasing it as a single. Bobby Arvon recorded an updated version in 1983 for Season 11, with the same lyrics as the version used for seasons 3-10. Pratt & McClain's album version of the song peaked at No. 5 on the Billboard Hot 100,[6] No. 7 on the Easy Listening chart,[6] and No. 31 on the UK Singles Chart.[7] In Canada, "Happy Days" reached No. 3.[8] Australian band Silver Studs did a rendition of the theme for their debut album. It became their biggest hit single in Australia, reaching No. 4 in June 1976.[9] In 2014, a re-recording of the song was used in commercials for Target. An instrumental version of the song plays in the background of some of the "Cooking with Sara" Flash games.
