Tour itinerary [45 concerts]
Exact setlists from the very early days remain unknown. It is known Queen used to play some Smile tracks (Doing Alright, maybe See What A Fool I've Been), a couple of their own tracks from the yet-to-be-released debut LP (Keep Yourself Alive, Liar, Great King Rat, Modern Times Rock'n'roll, Son And Daughter), the famous never-released track Hangman and some more pearls such as an early version of Stone Cold Crazy, Jesus and Night Comes Down (the latter two were never played live again after 1973). The concerts were always finished with a medley of rock'n'roll covers. The only known recordings from this era are in private collections of Brian May, former Queen bass players or Queen Productions.
There have been rumours that the band changed their name from 'Smile' to 'Queen' much later than after the Truro 1970 concert. I've already found two people who attended the Hertford concert and they confirmed that the band changed their name to 'Queen' shortly before the Hertford gig (after the Liverpool concert). But - there are flyers from summer 1970 advertising the band as 'Queen'. So it's just possible they were advertised as 'Smile' on some flyers during summer 1970 because Smile were quite a well known band in the university circles.
