"When the Girl in Your Arms Is the Girl in Your Heart" is a 1961 hit by Cliff Richard written by the songwriting team of Sid Tepper and Roy Bennett who would contribute fifteen songs to the Cliff Richard canon including his career record "The Young Ones". Produced by Richard's regular producer Norrie Paramor, "When the Girl in Your Arms..." featured backing by the Norrie Paramor Orchestra with vocal support from the Mike Sammes Singers. Richard's own group the Shadows backed him on the B-side "Got a Funny Feeling".

Recorded in January 1961, "When the Girl in Your Arms..." was not released until that October as the first advance single for the Cliff Richard movie vehicle The Young Ones. The track reached a chart peak of #3 in the UK and gave Richard a #1 hit in the Netherlands, Norway (for eight weeks) and South Africa. A #2 hit in Australia and Ireland, Richard's "When the Girl in Your Arms..." was also a hit in Belgium/Flemish Region (#4), Belgium/Wallonia (#10) and New Zealand (#7).

Although Cliff Richard had a deal for US distribution with ABC-Paramount - who in 1959 had released his only US hit (as of 1961) "Living Doll" (#30) - "When the Girl in Your Arms..." was not given a US release concurrent with its UK charting, as ABC-Parmamount felt it prudent to await the American opening of the track's parent movie The Young Ones. Connie Francis heard Richard's hit while visiting the UK and in an unusual move Francis - whose singles were typically remakes of traditional pop standards or original material - covered Richard's UK hit in a 2 November 1961 session in New York City produced by Arnold Maxin with Don Costa as arranger/conductor. Entitled "When the Boy in Your Arms (Is the Boy in Your Heart)", Francis' version reached #10 on the Billboard Hot 100 in January 1962 and #8 in Cash Box. The single's B-side "Baby's First Christmas" also became a chart hit over the 1961 holiday season reaching #26.
