Erik Wilson writes:
"The horns also do a raucous trill near the end of the first movement — one of Mahler’s funniest moments I think — and it’s very restrained under Bychkov as already pointed out by Chris. To be fair, in the score it’s only the fourth horn part, and the rest are doing something else. But I love hearing it the way we do on Honeck, Levi, and Fischer."
Which Fischer? Ivan, Adam, or Thierry?
