Go slowly around, welcoming each one for lively dance (8)
I believe the answer is:
galliard
'dance' is the definition.
(I've seen this before)
'go slowly around welcoming each one for lively' is the wordplay.
I cannot really understand how this works, but
'each' could be 'all' (similar in meaning) and 'all' is found within the answer.
'one' could be 'i' (roman numeral) and 'i' is found within the answer.
The remaining letters 'gard' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for galliard that I've seen before include "(Elizabethan) dance" , "Lively old dance" , "Pacific kingdom" .)
