"Jeans On" is a song by British musician David Dundas from his 1977 self-titled debut album.

Released as a single the previous year, it was first featured as a television advertising jingle in The United Kingdom for Brutus Jeans.

The popularity of the original commercial eventually led to the recording of "Jeans On" as a full-length song, with some lyrical changes.

It became a chart hit all over Western and Northern Europe, including a number 1 in West Germany.

Dundas also recorded a French language version of the song, titled "Blue Jeans".
