Deryk Barker asks if Bernstein ever conducted Mahler's Third.  Yes.  He
recorded it at least twice.  I know only the first, part of his original
Mahler cycle, and I consider it one of the finest recordings of anything.
The movement with the posthorn solo is one I would gladly hear in my last
moments of life.  If I have any reservations about it, it would be that I
have heard a final movement that moved me more, in a live performance at
Tanglewood (by none other than Ozawa, which will no doubt ruin my
credibility with some, but it made time stand still while it lasted.)
