Maybe Annie Hall's content to follow Mike round America (7)
I believe the answer is:
musical
'maybe annie' is the definition.
I can't tell whether this defines the answer.
'hall's content to follow mike round america' is the wordplay.
'content' means to look at the middle letters.
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'follow mike round' becomes 'music' (I am not sure about this - if you are sure you should believe this answer much more).
'america' becomes 'a' (common abbreviation eg in USA).
The centre of 'halls' is 'l'.
'music'+'a'='musica'
'l' put after 'musica' is 'MUSICAL'.
Can you help me to learn more?
(Other definitions for musical that I've seen before include "Eg, Les Miserables" , "Oliver perhaps" , "Eg, Cats or Evita" , "Theatrical production featuring songs and dancing" , "Form of theatre" .)
