Festival date: around Saint Marina? (9)
I believe the answer is:
woodstock
'festival' is the definition.
Both the definition and answer are singular nouns.
Maybe there's an association between them I don't understand?
'date around saint marina?' is the wordplay.
'date' becomes 'woo' (I can't justify this - if you can you should give a lot more credence to this answer).
'around' is an insertion indicator.
'saint' becomes 'st' (abbreviation).
'marina?' becomes 'dock' (marina is a kind of dock).
'st' inserted inside 'dock' is 'dstock'.
'woo'+'dstock'='WOODSTOCK'
Can you help me to learn more?
(Other definitions for woodstock that I've seen before include "Pivotal American music festival in 1969" , "1969 US rock festival" , "Log pile" , "Famous US rock festival" , "near Oxford" .)
