Queen will release new track Let Me Be In Your Heart Again to help raise funds for Coca-Cola's RED campaign to benefit the Global Fund, which fights AIDS, tuberculosis and malaria.
The unreleased tune, which was recorded by the band and frontman Freddie Mercury before his death from AIDS-related causes in 1991, will feature on the group's upcoming Queen Forever compilation.
Guitarist Brian May says, "It's been 23 years since the world lost our beloved Freddie Mercury. We've made extraordinary progress in the fight against AIDS in that time. But we cannot simply rest on the fact that the treatment is available. We must ensure that it is provided.
"Roger (Taylor) and I are proud to lend this rediscovered song to the RED campaign, in the hope that Freddie's powerful voice can inspire the world yet again."
The track was recorded during sessions for Queen's 1984 album, The Works, and Taylor explains, "It somehow didn't get used, or it didn't get finished, I guess, and it just got put aside and forgotten. I think Brian discovered it again, and I'd completely forgotten about it, I have to say. So we did a little work on it. We did a few backing vocals on it and there it is, with all of the original instruments and the rhythm section and guitar as it was recorded at the time. That was a nice surprise for me."
