Ban miners from a musical (6)
I believe the answer is:
barnum
'a musical' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
'ban miners' is the wordplay.
'ban' becomes 'bar' (I've seen this in other clues).
'miners' becomes 'NUM' (National Union of Mineworkers).
'bar'+'num'='BARNUM'
'from' is the link.
Can you help me to learn more?
(Other definitions for barnum that I've seen before include "Bailey's circus partner, d. 1891" , "US creator of "The Greatest Show On Earth"" , "With Bailey, he ran a famous circus" , "US showman who popularized the circus" , "US showman, Bailey's partner" .)
