Odd, receiving odd tattoo? (4,4)
I believe the answer is:
drum roll
'tattoo?' is the definition.
(I've seen this before)
'odd receiving odd' is the wordplay.
'odd' becomes 'rum' (rum can mean strange or dubious).
'receiving' means one lot of letters goes inside another (I've seen this in other clues).
'odd' becomes 'droll' (I've seen this in another clue).
'rum' placed into 'droll' is 'DRUM ROLL'.
(Other definitions for drum roll that I've seen before include "Rapid percussive sound" , "Tattoo" , "Haydn symphony" , "musical introduction?" .)
