The composer had the original idea for the piece during a heat wave in July 1946 and finished the work in February 1948. It was originally an instrumental piece; the lyrics, about someone asking another to join them for a ride in a sleigh, were written by Mitchell Parish in 1950. The orchestral version was first recorded in 1949 by Arthur Fiedler and the Boston Pops Orchestra. Sleigh Ride was a hit record on RCA Victor Red Seal 49-0515 (45 rpm) / 10-1484 (78 rpm), and has become a signature song for the orchestra. The 45 rpm version was originally issued on red vinyl. The Pops has also recorded the song with John Williams, their conductor from 1979 to 1995, and Keith Lockhart, their current conductor. [END]
