It was the first S Club 7 single to be released as a double A-side, later followed by "Say Goodbye" and "Love Ain't Gonna Wait for You" in 2003.

The single contains an exclusive B-side, "Down at Club S", which was performed during episode three of Miami 7, "The Blue Chevy".

It is very much in a similar style to "You're My Number One", and was co-written by Simon Franglen and Angela Lupino, who also wrote "Gonna Change the World" for the group.

Throughout, S Club 7 are performing a dance routine in front of a white background.

On 9 October 2024, British supermarket chain Waitrose released an advert featuring the reformed S Club dancing to a new Jax Jones remix of "You're My Number One" (titled "You’re My No.1").
