Old bandmaster provided by America (5)
I believe the answer is:
sousa
'old bandmaster' is the definition.
(I know that Sousa is a bandmaster)
'provided by america' is the wordplay.
'provided' becomes 'so' (I've seen this in other clues).
'by' says to put letters next to each other.
'america' becomes 'usa' (synonyms).
'so'+'usa'='SOUSA'
(Other definitions for sousa that I've seen before include "John Philip -, composer of famous marches (The Stars and Stripes for Ever)" , "March man?" , "John Philip ---, US bandmaster" , "John Philip --, American march composer" , "US composer of marches" .)
