"Merry Christmas, Darling" by The Carpenters was written by Richard Carpenter & Frank Pooler and originally recorded in 1970. At the time, it was only available on a 7" single from A&M Records (1236) and later in 1974 reissued as A&M 1648 and in 1977 as A&M 1991. The single went to number one on Billboard's Christmas singles chart in 1970, and did again in 1971 and 1973.
I used to listen it to on a 45 in 1973 and in 1970, I listened to it on my transistor radio. Still have it on a 45!
