British singer Ralph McTell has teamed up with the homeless charity Crisis to re-release his 1969 hit Streets of London, featuring guest vocalist Annie Lennox and a choir made up of people who've benefited from the work of the charity.

Proceeds from the single will go towards Crisis, and McTell commented 'When the idea of a single to support Crisis was mooted, I was very pleased that it might help raise awareness of the charity’s work and the wider issue of homelessness... I was also thrilled that the wonderful Annie Lennox was prepared to lend her voice to a new recording, and when I discovered that Crisis had its own choir, it offered the perfect opportunity to create a new and exciting version of a song so many people know'.
