Mountain range seen when holding record (4)
I believe the answer is:
alps
'mountain range' is the definition.
(Alps is an example)
'when holding record' is the wordplay.
'when' becomes 'as' (eg 'when I walked' means 'as I walked').
'holding' means one lot of letters goes inside another.
'record' becomes 'L-P' (abbreviation for long play record).
'as' placed around 'lp' is 'ALPS'.
'seen' is the link.
(Other definitions for alps that I've seen before include "Pals seen in mountains" , "& 11 their highest peak" , "Mountain pastures" , "Pals put on the mountains" , "Mountains in Central Europe" .)
