Norma Waterson recorded Freddie Mercury's "Love of My Life" on her solo album, The Very Thought of You, as well as Lal's song, "Reply to Joe Haines", which is a direct rebuke to Haines for his offensive remarks about Mercury... Norma's description of the song:

At once a lament for/tribute to Freddie Mercury (real surname Bulsara, as in this song} & a stinging rejoinder to Joe Haines. Norma's own note refers to the 'white knuckle fury of my sister Lal's 'Reply to Joe Haines' (originally called 'An Open Letter to Joe Haines') which is just that. A reply to the iniquitous article written by that man on the subject of Freddie Mercury's disclosure that he was HIV positive (indeed that he had full blown AIDS) and which the Daily Mirror saw fit to print.'

And de Danaan did a wonderful Celtoid instumental version of "Bohemian Rhapsody" that they re-titled "Hibernian Rhapsody", on their album of the same name.

Good musicians are interested in all sorts of music, and garner songs, styles and ideas that feed into their own music!
