A second circle of light coming up around lead in kitsch musical (8)
I believe the answer is:
oklahoma
'musical' is the definition.
(I've seen this before)
'a second circle of light coming up around lead in kitsch' is the wordplay.
'second' becomes 'mo' (both are short periods of time**).
'circle of light' becomes 'halo' (I've seen this before).
'coming up' shows that the letters should be reversed in order.
'around' is an insertion indicator.
'lead in' suggests taking the first letters.
The initial letter of 'kitsch' is 'k'.
'a'+'mo'+'halo'='amohalo'
'amohalo' backwards is 'olahoma'.
'olahoma' placed around 'k' is 'OKLAHOMA'.
(Other definitions for oklahoma that I've seen before include "Young woman" , "US State and musical drama" , "American state and name of great musical" , "US state, joined in 1907" , "US state - Rodgers and Hammerstein musical" .)
