That concert, being heard live for the first time in the soon to be released Queen: Live at the Rainbow ’74, marked the culmination of the band’s countrywide tour, their first as headliners - hot on the heels of a tour supporting Mott the Hoople, late in 1973, on which they were widely regarded as having blown the hit band off the stage. Queen got rave reviews, almost unheard of for a support band, and it was obvious that in future they would be top of the bill. The band’s momentum had been building since the release of their eponymous album in July 1973 and, following their success on the Mott tour, at the beginning of 1974 they were tipped as Band of the Year in UK music paper Disc and Music Echo.
Just before the March Rainbow gig, Queen performed their new single Seven Seas of Rhye on must-see UK TV music show Top of the Pops. The highly coveted slot was a lucky break - they filled in for an absent David Bowie, who was unavailable - and the band made the most of it, delivering a thrilling performance that pushed the song into the Top 10.
