My clue of the day and LOI was 4dn. Even though I wrote the actual answer on the side well before the end, the smooth surface of the clue distracted me for ages from finding the anagram indicator. Well done, setter! Thanks for a very enjoyable puzzle.
Clues are in blue, with definitions underlined. Answers are in BOLD CAPS, then wordplay. (ABC*) means ‘anagram of ABC’, with the anagram indicator in bold italics. Deletions are in [square brackets].
Across
1 Hot tunes please old setter (4,5)
HAIR SPRAY: H (hot) / AIRS (tunes) / PRAY (old word for please).

PRAIRIE: P.R. / AIR / I.E.
11 Horse unseats one big bird (5)
