Run out and play guitar on dais (7)
I believe the answer is:
rostrum
'dais' is the definition.
('rostrum' can be a synonym of 'dais')
'run out and play guitar' is the wordplay.
'run out' becomes 'ro' (cricket abbreviation).
'and' means one lot of letters go next to another.
'play guitar' becomes 'strum' (I've seen this before).
'ro'+'strum'='ROSTRUM'
'on' acts as a link.
(Other definitions for rostrum that I've seen before include "Podium" , "beak" , "Platform for public speakers" , "Raised platform" , "stage" .)
