Part of veteran thematic song? (6)

I believe the answer is:

anthem

'song?' is the definition.
(anthem is a kind of song)

'part of veteran thematic' is the wordplay.
'part of' indicates the answer is hidden within the clue.
'ANTHEM' is hidden in the letters of 'veteran thematic'.

(Other definitions for anthem that I've seen before include "National or church song" , "Song of praise or loyalty" , "National hymn" , "Internationale?" , "Uplifting song -- the man (anag)" .)

I've seen this clue in The Times.
