From the wiki: “‘Heartbeat’ is a rockabilly song credited to Bob Montgomery and Norman Petty, and recorded originally by Buddy Holly in 1958. It was the last Buddy Holly single to be released during his lifetime. It charted low on the Billboard Hot 100 but has proven to be more popular in the UK, where Holly’s recording went Top-30. The England Sisters, also known as the Dale Sisters, recorded a cover in 1960 that peaked at #33 on the UK Singles chart.
“‘Heartbeat’ covers would subsequently reach the UK Top Ten twice: In 1975, for ’50s & ’60s revival band Showaddywaddy, and again in 1992 with the arrangement Nick Berry recorded as the theme to the Heartbeat TV series.
“Herman’s Hermits — who had originally been named The Heartbeats after the song — recorded the song in 1965. The Hollies, who had named themselves after Buddy Holly, made their only attempt at having a hit remake of a Buddy Holly song with a 1980 single release of ‘Heartbeat’ that failed to chart.”
