Richard gave this new tape release HIS BLESSING and refused to let anyone hear anything OR READ the ROTOQ script at the 2011 convention in Atlantic City. He forbid them from doing so. A lot of that became Shock Treatment anyhow.
That's not true - the script at the 2011 convention was "Rocky Horror Shows His Heels" ("Revenge" was a sequel script written in the Nineties). To be fair, most of "Heels" is unrelated to Shocky - Richard only reused some (but not all) of the music.
I could be wrong, but I don't think Richard flat out told them not to read "Heels" at the Con; Richard was angry because they wanted to show 'The Rocki Whore Picture Show' (which they didn't in the end), and cancelling the RHSHH reading was just an attempt to get on Richard's good graces.
But I could be wrong; that's the version I heard.
