It can be heard during the TV show's opening and closing credits as it runs in #perpetualRerunSyndication. "Happy Days" was first recorded in 1974 by #JimHaas with a group of other #sessionSingers for the first two seasons. These versions were used only during the closing credits of Seasons 1 and 2.
