Performance from old lady, character on main platform (9)
I believe the answer is:
rigmarole
'performance' is the definition.
(I've seen this before)
'from old lady character on main platform' is the wordplay.
I cannot quite see how this works, but
'from' could be 'o' (I've seen this in other clues) and 'o' is found in the answer.
'character' could be 'r' and 'r' is found in the answer.
'old lady' could be 'ma' (both can informally mean mother) and 'ma' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for rigmarole that I've seen before include "Rambling account" , "boring series" , "Nonsensical procedure" , "garbled nonsense" , "Long, complicated and confusing procedure" .)
