Richard Carpenter released several tracks decades after his sister Karen died in 1983, leaving a multitude of unfinished work. One track, released on the "Interpretations" compilation album in 1995, included Karen's lead vocal for the song "Tryin' to Get the Feeling Again" which had previously been recorded and released by Barry Manilow. The lead had been lost for years on a mislabelled tape. Strings, piano, and backup singers were added to the sound of Karen's lead vocal, while Richard left the sound of her turning the lead sheet over in the finished product. Another track was Karen's cover "The Rainbow Connection", which had been written by Kenny Ascher and Paul Williams for Jim Henson to sing as Kermit the Frog in "The Muppet Movie" (1979). Recording it only a year later, Richard claims that Karen just did not like the song and that was why it was omitted from their 1981 album, "Made In America". A toy piano, choir, and strings were added against Karen's vocals. The song was released in 2001 on the album "As Time Goes By", considered the final studio album of the duo.
