"Yesterday, When I Was Mad" is a single by English synthpop duo Pet Shop Boys released as the fifth and last single from their 1993 album Very. The single peaked at #13 on the UK Singles Chart and #4 on the U.S. BillboardHot Dance Club Play charts. The song was remixed by Jam & Spoon for its single release, among other things removing a compression effect applied to Tennant's voice during the verses. The B-sides included a cover of the Noël Coward song If Love Were All.
The song is about the stresses of touring and how being away from loved ones can make musicians unwilling to trust others or carry on with their career, contrasting it with the humour of ironic, pretentious or rude things people say to touring musicians. Tennant has said that many of the lines in the song, such as 'And someone said, "It's fabulous you're still around today-you've both made such a little go a very long way!"' actually happened.
The track includes Chris Lowe in one of his rare lead-vocals performances, singing through a vocoder. The Boys claimed to have been unaware at the time of release that Euroboy was also the name of a softcore gay pornographic magazine.
It was occasionally performed live on the Asian leg of the band's 1994 Discovery tour.
