Tenor, beloved Italian, touring America (6)
I believe the answer is:
caruso
'tenor' is the definition.
(singer Enrico Caruso)
'beloved italian touring america' is the wordplay.
'beloved italian' becomes 'caro' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'touring' means one lot of letters goes inside another (touring can mean going round).
'america' becomes 'US' (United States).
'caro' placed around 'us' is 'CARUSO'.
Can you help me to learn more?
(Other definitions for caruso that I've seen before include "Opera singer" , "Enrico ...... was famous Italian tenor" , "Singer Enrico" , "Enrico ---, early C20 tenor" , "Classical tenor" .)
