I haven´t heard that much of queen live, but of all (the few) medleys I´ve heard I like most the A Day At The Apollo 77 medley with killer queen- good old-fashioned lover boy-the millionaire walz-you´r my best friend-bring back that leroy brown.
The late '77 - early '78 ones:
'Death On Two Legs', 'Killer Queen', 'Lover Boy', 'I'm In Love With My Car', 'Get Down Make Love', 'Millionaire Waltz', and 'You're My Best Friend'.
Seven songs, no 'Bicycle Race' - heaven!
