Queen

What was Queen's first ever single??

[WESTHAM666]

Seven Seas of Rhye

[wideboy]

That was their first HIT. What about this:-

Soon after the failed single, 'Keep Yourself Alive', they issued a self-titled album, which was an interesting fusion of 70s glam and late 60s heavy rock (it had been preceded by a Mercury 'solo' single, a cover of the Beach Boys' 'I Can Hear Music', credited to Larry Lurex). Queen toured extensively and recorded a second album, which fulfilled their early promise by reaching the UK Top 5. Soon afterwards, 'Seven Seas Of Rhye' gave them their first hit single (UK number 10), while "Sheer Heart Attack" consolidated their commercial standing by reaching number 2 in the UK album charts.

Some folks consider "Earth b/w Step On It" to be the first Queen single, but technically that was by Smile, which only included Brian May and Roger Taylor.  Of course, those same two are currently touring with Paul Rodgers and calling themselves "Queen"....
