" Stranger on the Shore " is a piece for clarinet written by Acker Bilk for his young daughter and originally named "Jenny" after her. The tune was written on a single scrap of paper by Bilk and handed over to Leon Young (1916-1991) who crafted the string arrangement, including the characteristic harmonic shifts at the very end. The recording was subsequently used as the theme tune of a BBC TV drama serial for young people, Stranger on the Shore . It was first released in 1961 in the UK, then in the US, and reached number 1 in the US and number 2 in the UK. In May 1969, the crew of Apollo 10 took "Stranger on the Shore" on their mission to the moon. Gene Cernan , a member of the crew, included the tune on a cassette tape used in the command module of the Apollo spacecraft.
