Sang going round hotel, becoming animated (8)
I believe the answer is:
thrilled
'animated' is the definition.
'sang going round hotel' is the wordplay.
I cannot really see how this works, but
'hotel' could be 'h' (phonetic alphabet: alpha, bravo, charlie etc.) and 'h' is located in the answer.
'sang' could be 'trilled' (trilling is a kind of singing) and 'trilled' is found within the leftover letters.
No letters remain.
This may be the basis of clue (or it may be nonsense).
'becoming' acts as a link.
(Other definitions for thrilled that I've seen before include "Feeling intense pleasurable excitement" , "Exhilarated" , "Excited and pleased" , "Delighted" .)
