Conductor of bus expelling us, along with numbers of Germans, we hear (10)
I believe the answer is:
bandleader
'conductor' is the definition.
(bandleader is a kind of conductor)
'bus expelling us along with numbers of germans we hear' is the wordplay.
I cannot really see how this works, but
'with' could be 'and' and 'and' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for bandleader that I've seen before include "Music supremo" , "Music director" , "He conducted" , "Ted Heath was one" , "Top musician" .)
