'scots keep' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'red sea nightclub running' is the wordplay.
'running' indicates anagramming the letters (the letters run around to different places).
'red'+'sea'+'nightclub'='redseanightclub'
'redseanightclub' with letters rearranged gives 'EDINBURGH CASTLE'.

Can you help me to learn more?

(Another definition for edinburgh castle that I've seen is " big old building".)
