15D Musical interval for actress dame, briefly? (5) 17A Bury football team in Italy (5) inter??? doesn't seem right!

Yes, it could be "inter" as in Inter Milan and inter meaning to bury.

17A. Milan (as in Inter Milan)

[Yarmite]

15D. Could this be Dench (Judi) she played in Merry Wives The Musical from The Royal Shakespeare Company, Judi played Mistress Quickly. As far as I know this was the only musical she was ever in therefore it was brief.

Yarmite the definition is 'Musical Interval 'and the wordplay
'actress Dane briefly'

A third is a note separated from another by a this interval.

Thora Hird is a Dame and an actress and is briefly T Hird

Hope this helps you understand my answer
