Group of musical mimics curtailed trip, reportedly barred on Scottish isle (7,4)
I believe the answer is:
tribute band
'group' is the definition.
(I know that tribute band is a type of cover band)
'curtailed trip reportedly barred on scottish isle' is the wordplay.
'curtailed trip' becomes 'tri' (I can't explain this - if you can you should believe this answer much more).
'reportedly' shows a homophone (sound like).
'barred' becomes 'banned' (I've seen this before).
'on' says to put letters next to each other.
'scottish isle' becomes 'bute' (I've seen this before).
'banned' is a homophone of 'band'.
'band' put after 'bute' is 'buteband'.
'tri'+'buteband'='TRIBUTE BAND'
'of musical mimics' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Another definition for tribute band that I've seen is " Group after another".)
