Thus the little marsupial's protected by parents in places to play (5,5)
-U(?)---,R---S.
That should give help with remaining two M acrosses (Feb and Oct) 10/17.
No idea about 3d, 7d,14d.
Can't parse 13d (striking). Spain?

[Lie-in King]

2d Music rooms - 'sic + roo' (thus + little marsupial, in) 'mums'

13d Striking - 'string' (yarn, about) 'Ik(E-spana)'

Hi olegrahl - it's always nice to include the clue to queries such as the one for 13d, so that people without the puzzle can more readily help :-)

Music rooms - sic(thus) & roo (Marsupial) inside mums (Parents)

[Marienkaefer]

The 13dn clue in the print edition is "without piano, band leader is impressive"

[olegrahl]

Whereas the online version has "Impressive yarn about Eisenhower liberating Spain."
Not the only alternative clue. 19d on line is "Many extremely powerful Russian banks hold it" (plural) while print clue is quite different.

[Mamyalynne]

Seems they differ on just those two clues - odd isn't it.
