"Heroes" (styled with double quotation marks) is a song written by David Bowie and Brian Eno in 1977. Produced by Bowie and Tony Visconti, it was released both as a single and as the title track of the album "Heroes". A product of Bowie's fertile 'Berlin' period, life in the city was crystallized into a tale of two lovers who come together in the shadow of the 'Wall of Shame' (though here "the shame was on the other side"). While not a huge hit in the UK or US at the time, "Heroes" has gone on to become one of Bowie's signature songs and is well known today for its appearance in numerous advertisements. It has been cited as Bowie's second most covered song after "Rebel Rebel". The title of the song is a reference to the 1975 track "Hero" by the German band Neu!, whom Bowie and Eno admired. It was one of the early tracks recorded during the album sessions, but remained an instrumental until towards the end of production. The quotation marks in the title of the song, a deliberate affectation, were designed to impart an ironic quality on the otherwise highly romantic, even triumphant, words and music. Producer Tony Visconti took credit for inspiring the image of the lovers kissing "by the wall", when he and backing vocalist Antonia Maaß embraced in front of Bowie as he looked out of the Hansa Studio window.9 Bowie's habit in the period following the song's release was to say that the protagonists were based on an anonymous young couple but Visconti, who was married to Mary Hopkin at the time, contends that Bowie was protecting him and his affair with Maaß. Bowie confirmed this in 2003.
