Euphoria provided by a topless Bond (7)
I believe the answer is:
elation
'euphoria' is the definition.
(I've seen this before)
'a topless bond' is the wordplay.
'a topless' means to remove the first letter.
'bond' becomes 'relation' (bond can mean a relation or connection).
'relation' with its first letter removed is 'ELATION'.
'provided by' is the link.
(Other definitions for elation that I've seen before include "'High spirits, exhilaration (7)'" , "Delight, ecstasy" , "Ecstasy -- toenail (anag)" , "Transport" , "Feeling of delight or pride" .)
