Nofi, how you take care of me!
With the exception of Pictures of Home (which was only played post reunion), all tracks from Machine Head saw live renditions (that album was written with the goal to make it "work live" after a lot of the predecessor Fireball's tracks - almost all - had not translated well to the stage): Highway Star, Lazy and Space Trucking (replacing Mandrake Root as the tour de force for extended Lord and Blackmore solos) became live staples almost at once, Smoke on the Water (after an initial hesitant start, no one within Purple thought much of the number) followed soon, Maybe I'm a Leo was played for a while too (to make Roger happy, it was largely his number), even the slated (and failed) single Never Before was initially played (but probably already dropped by the time they hit the US for another countless tour). Older stuff that remained was (rarely) Fireball, (always) Child in Time, (sometimes) Strange Kind of Woman, Black Night, Speed King and Lucille, the Little Richard chestnut.
In truth, Purple changed its set list during Mark II days too rarely, the band excelled in giving different renditions of the songs every night, extending or cutting them short at will, but the set list pretty much repeated itself, thanks to a largely inflexible Ritchie Blackmore in that department. If Ritchie didn't want to play something live, it wasn't played, end of story.
For instance, the only song from Who Do We Think We Are that saw live performance during Mark II's halcyon days was Mary Long. Blackmore flatly refused to play My Woman from Tokyo (though he wrote it, but disliked that it was in a major key) and post Mark II reunion it only entered the set in a ravaged form excluding the lovely middle eight (mainly Gillan's do, Blackmore found it too off the wall and still wouldn't play that part even in the 80ies and 90ies).
