"Jeans On" put David Dundas on the British charts for 13 weeks in 1976, three of which were spent in the Top Five that summer. Roger Greenaway and Dundas co-wrote the song, which came from a jingle Dundas had penned for a commercial for Brutus Jeans in the U.K. Released by Air/Chrysalis, the single crossed the Atlantic early the next year to land in the Top 20 in the states. ("Jeans On" can be found on the compilation Super Hits of the '70s, Vol. 19.) Dundas followed up with "Another Funny Honeymoon" in 1977, and the single climbed into the Top 40 in the U.K. Chrysalis issued a pair of his albums, neither of which made much of a splash. He turned his talents toward composing, and his television and movie credits include How to Get Ahead in Advertising, Sometime Never, Dark City, Sleepers, and Freddie as F.R.O.7. He and Rick Wentworth co-wrote Withnail and I's score. In addition to collaborating with Greenaway and Wentworth, Dundas's "Jeans On" has also been covered by Andre Williams and sampled by Fatboy Slim. David Dundas, the son of the Marquess of Zetland, was born in Oxford and at first pursued acting before turning to music. He found work in movies, television, and the theater. In 1968, he appeared in Prudence and the Pill with David Niven.
