The 'Rocket Man' singer spent two nights in intensive care after becoming "violently ill".
The previously unreleased ballad will feature on Queen's forthcoming album 'Queen Forever'
Queen's latest album will feature a stripped-down version of Freddie Mercury's solo hit 'Love Kills'.
The late frontman first released the disco single in 1984 and now his bandmates are sharing an alternative version of his work.
Recorded before his death in 1991, the long-hidden rendition – with Freddie on vocals – replaces the original sound of synth with powerful guitars turning the single from a dance track into a ballad.
The never-before-heard song is available to buy or download as part of Queen's forthcoming album, 'Queen Forever', set for release in November.
Their new album features three previously unreleased tracks recorded with Mercury, including a collaboration with Michael Jackson.
