Rob120 said: "Yes, the entire score was re-orchestrated and vocal parts rearranged, however when you license the show you are given lead sheets instead of full charts so there is no “set” orchestration to the show. Every version is different. If you listen to a couple of cast recordings you will immediately notice the differences."
This is not entirely true. The licensed ROCKY HORROR is NOT the Revival Version of the show. You receive the revised tour that went out after the show first opened.
The scores have recently (within the last 5 years) been typeset, and are NOT lead sheets. You receive the original orchestration, (Keys, Synth, Guitar, Bass, Sax.). I've seen the old parts and they were not lead sheets either. So, that comment is odd to me.
