Just found this crossword half-done in a pile of paperwork, so wanted to finish it.

12A Nation of privileged 5s? [the answer to 5A was MILLER]
U?A?D?
Think it's UGANDA, although "Nation of privileged millers/Millers?"/"Nation of privileged fives" - don't get it either way (4 of the answers were songs by Glenn Miller, one was a play by Arthur Miller)

4D Old stinker last to leave - blow it!
O?O?
Think it's OBOE
stinker = BOer? (i.e. sb with BO)

Can anyone explain these clues please?

4d.Oboe( old= o, stinker= bo, last to leave= e)

Bit obscure but could it be
U(privileged/posh) G(lenn) and A(rthur) ?
