Could some answer these queries, which I posted in Another Place to no avail:

We are told that Minkowski played the 'Er don Guet' section no less than three times in Bizet's 'L'Arlesienne'. Which bit is this?

We are told that there is a delightful pre-echo of a Sousa march in the "Gratias" of Schubert's Mass in E flat major. Which Sousa march?
