Where the Pied Piper played (7)
I believe the answer is:
hamelin
'where the pied piper played' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hamelin that I've seen before include "Town with a rodent problem" , "Pied Piper location" , "Town once plagued by rats" , "Town employing the Pied Piper" .)
