Brian May has said a long-forgotten Queen track is "crying out to be... brought into the world".
The Sun reported that the song, featuring the late Freddie Mercury on vocals, was penned more than 30 years ago.
Brian wrote on his blog: "Some Queen magic is happening... I feel it in my bones.
"It's annoying to have to be secretive, but I guess I have to, for now.
"The track we dusted off today has the four of us - Freddie, John (Deacon), Roger (Taylor) and myself - playing together on a track we'd all forgotten about that was never finished."
The guitarist added: "It sounds so fresh...I got quite emotional hearing some of it. Some rough takes, some discussion and banter, and then a really good take... It's crying out to be finally brought into the world."
"What's great is that nobody has got hold of this and leaked it... I can't help but feel a buzz."
