Hippies quietly elope, running south of river? (6,6)
I believe the answer is:
flower people
'hippies' is the definition.
(I've seen this before)
'quietly elope running south of river?' is the wordplay.
'quietly' becomes 'p' (p for piano and quiet).
'running' indicates anagramming the letters.
'south of' is a charade indicator (letters next to each other).
'river?' becomes 'flower' (a river flows).
'elope' anagrammed gives 'eople'.
'p'+'eople'='people'
'people' put after 'flower' is 'FLOWER PEOPLE'.
(Other definitions for flower people that I've seen before include "Hippies" , "Florists" , "advocates of peace?" .)
