The song was revived and turned into a slow jam by American singer Aaliyah for her debut studio album Age Ain't Nothing but a Number. Released as the record's second single, it peaked at #6 on the Billboard Hot 100.

It was later revealed the pair married on August 31, 1994, and Aaliyah had lied about her age on the marriage certificate. The marriage was annulled the following February when Aaliyah's parents found out.

The credits for Endless reveal that the song was recorded at London's Abbey Road studio made famous by The Beatles.
