A dance and a drink with some of the band (5)
I believe the answer is:
rumba
'a dance' is the definition.
(rumba is a type of dance)
'a drink with some of the band' is the wordplay.
'a drink with' becomes 'rum' (I can't explain this - if you can you should believe this answer much more).
'some of' means to look at the middle letters (I've seen 'some' mean this).
'the band' becomes 'rabato' (rabato is a kind of band).
The central letters of 'rabato' are 'ba'.
'rum'+'ba'='RUMBA'
'and' is the link.
Can you help me to learn more?
(Other definitions for rumba that I've seen before include "Latin beat" , "South American dance" , "Dance originating in Cuba" , "Style of dance" , "Lively Cuban dance" .)
