This one has always been a favourite of mine - I wished it could have been a single at the time, but really it would not have worked to put something out as a single on which Freddie was not the principal singer. Of course he DOES sing the middle eight - and beautifully too. The solo in Sail Away was always intended to be Killer Queen revisited in a different way (for reasons which are obvious to me, but do not need going into!). The solo starts the same way, on one guitar, and is then enjoined by two others which add in “Bell” type harmonies, a la Mantovani(which I think I talked about elsewhere). In other words the first guitar hangs on, and each guitar that joins in adds in a harmony. The three guitar melodies go on for just a few notes, and then there is an interplay of “Bells” going upwards in pitch (rather than downwards as in Killer Queen), and there are FIVE of them and they step in very quickly! Now four of them keep playing in harmony until the end when they all become bound into a tight set of ascending chords leading back into the final chorus.
