Old AC/DC popular song covers in show (7)
I believe the answer is:
exhibit
'show' is the definition.
(exhibit is a kind of show)
'old acdc popular song covers' is the wordplay.
'old' becomes 'ex' (prefix meaning former or onetime).
'acdc' becomes 'bi' (AC/DC can informally mean bisexual).
'popular song' becomes 'hit' (a hit song).
'covers' means one lot of letters goes inside another.
'bi' put within 'hit' is 'hibit'.
'ex'+'hibit'='EXHIBIT'
'in' acts as a link.
(Other definitions for exhibit that I've seen before include "Present" , "parade" , "Publicly display" , "Give public show, as of paintings" , "Put on show" .)
