Picking up oddly smelly Scotsman's good vibrations (7)
I believe the answer is:
'good vibrations' is the definition.
Both the answer and definition are plural nouns.
Perhaps they are linked in a way I don't understand?
'picking up oddly smelly scotsman's' is the wordplay.
'picking up' says the letters should be written backwards.
'oddly' indicates alternate letters (letters in the odd-numbered positions are used).
'scotsman's' becomes 'braw' (I can't explain this - if you can you should believe this answer much more).
The alternate letters of 'smelly' are 'sel'.
'selbraw' backwards is 'WARBLES'.
Can you help me to learn more?
