Read where Plant asked for 48 hours to think it over. Tearing up the contract was his response.
Also read where Monty Python turned down 32 million for a world tour including Australia. They say they’re too old.
Having seen the live theater broadcast of the final Python show, yes the years are wearing. John Cleese repeatedly got lost if anyone else improvised a line (even with electronic cue cards).
And the material is a bit shop worn (the audience goes in knowing the punchlines). Interesting to see one more dust off but a tour would’ve been redundant.
