Singular bookings for players (4)
I believe the answer is:
gigs
'singular bookings' is the definition.
'gigs' can be an answer for 'bookings' (gig is a kind of booking). I am not sure about the 'singular' bit.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for gigs that I've seen before include "Pop/jazz band engagements" , "One-night musical stands" , "One-night music sessions" , "One-night-stand musical performances" .)
