On 1935’s Alma Mater:

Warburg told me about football.  It was Yale [vs] Princeton; he told me there are cheers, yelling, that they take the poles away and that people wear coats with that fur–raccoon.  And Princeton doesn’t like Yale, so I made a Yale boy marry a Princeton girl.  Kay Swift wrote it like a waltz.  She was friends with [George] Gershwin and an excellent songwriter on her own.  You can’t do that ballet any more.  It was only good at the time.  Of course [John] Martin probably said it was a disaster.
