Musician and detective on island propping up bar (8)
I believe the answer is:
bandsman
'musician' is the definition.
(bandsman is a kind of musician)
'detective on island propping up bar' is the wordplay.
'detective' becomes 'ds' (detective sergeant).
'on island' becomes 'man' (I can't justify this - if you can you should give a lot more credence to this answer).
'propping up' says to put letters next to each other.
'bar' becomes 'ban' (I've seen this before).
'ds'+'man'='dsman'
'dsman' put after 'ban' is 'BANDSMAN'.
'and' acts as a link.
Can you help me to learn more?
(Another definition for bandsman that I've seen is " musician".)
