"Home and Dry" is a song by British music group Pet Shop Boys released in 2002 as the first UK single and the second US single from their album Release. It reached the top 15 on the UK Singles Chart at #14 and peaked at #44 on the US Hot Dance Club Play.
One of the B-sides, "Sexy Northener", was also released as a promotional single in the U.S. and peaked at #15 on the US dance charts. It never got a commercial release though.
The song is infamous to Pet Shop Boys fans for its unusual video, directed by Wolfgang Tillmans, showing mice running across tracks and eating discarded food at Tottenham Court Road tube station. There are only several short shots of the duo performing. Many felt this was a strange choice for the video of a lead single, and that because of its commercially unappealing video, the song did not achieve the level of success it could have.
The track was remixed the same year by German trance duet Blank & Jones.
