Where we see Mike in the grip of drunken revellers? (7)
I believe the answer is:
karaoke
I'm afraid I can't even guess how this answer relates to the clue.
Can you help me to learn more?
(Other definitions for karaoke that I've seen before include "Pub singing (night)" , "Amateur musical entertainment" , "Amateur singing entertainment" , "Singing of songs over recorded backing tracks" , "Singalong entertainment" .)
