Dancing with many a wild mob (5)
I believe the answer is:
limbo
'dancing' is the definition.
(limbo is a type of dance)
'many a wild mob' is the wordplay.
'many a' becomes 'li' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'wild' indicates an anagram.
'mob' with letters rearranged gives 'mbo'.
'li'+'mbo'='LIMBO'
'with' is the link.
Can you help me to learn more?
(Other definitions for limbo that I've seen before include "passing under bar?" , "waiting time" , "Where things are lost or forgotten or being awaited" , "It's close to hell!" , "Period of indecision" .)
