Piano included in arrangement of eg Irish or Italian composer (8)

I believe the answer is:
respighi
'italian composer' is the definition.
The definition suggests a singular noun which matches the answer.
'piano included in arrangement of eg irish' is the wordplay.
'piano' becomes 'p' (musical abbreviation).
'included in' means one lot of letters goes inside another.
'arrangement of' indicates anagramming the letters.
'eg'+'irish'='egirish'
'egirish' anagrammed gives 'resighi'.
'p' put into 'resighi' is 'RESPIGHI'.
'or' acts as a link.
Can you help me to learn more?
(Other definitions for respighi that I've seen before include "Italian composer of symphonic poems, d. 1936 - hire pigs (anag)" , "Italian barman" , "Italian composer (The Pines of Rome)" , "Irish peg, oddly, for the Italian composer" , "Ottorino -, Ital. composer (The Pines of Rome)" .)
