Yesterday Once More, written by Richard Carpenter and John Bettis, is a hit song by the Carpenters from their 1973 album Now & Then. Thematically the song concerns reminiscing about songs of a generation gone by. It segues into a long medley, consisting of eight covers of 1960s tunes incorporated into a faux oldies radio program. The work takes up the entire B-side of the album.
The single version of the song peaked at number 2 on the Billboard Hot 100 chart, kept from the number 1 spot by Bad, Bad Leroy Brown by Jim Croce. It was the duo's fifth number two hit and made them the act with the second-most number two hits on the chart behind Madonna. The song also peaked at number 1 on the easy listening chart, becoming their eighth number 1 on that chart in four years. It is The Carpenters' biggest-selling record worldwide and their best-selling single in the UK, peaking at number 2. Richard Carpenter stated, on a Japanese documentary, that it was his favorite of all the songs that he had written. He has performed an instrumental version at concerts.
