Wandering nomad, a classic friend (5)

I believe the answer is:

damon

I'm a little stuck... Click here to teach me more about this clue!

'a classic friend' is the definition.
'damon' can be an answer for 'friend' (I have seen 'faithful friend' mean 'damon' so perhaps 'friend' could also mean 'damon'). I'm not certain of the 'a classic' bit.

'wandering nomad' is the wordplay.
'wandering' indicates an anagram.
'nomad' anagrammed gives 'DAMON'.

Can you help me to learn more?

(Other definitions for damon that I've seen before include "faithful friend" , "Matt --, US actor" , "Writer Runyon's first name" , "Pythias's friend" .)

I've seen this clue in the Evening Standard.
