Herbert Howells question

[brokenchord]

Hi

This is my first post here, although I've been lurking for a few months. Great forum, I've learned a lot. Can anyone help me with these newbie questions:

I've been trying through a piano piece by Herbert Howells: "There was a Most Beautiful Lady".  (I love his choral music).

Has anyone played this piece? It sounds like I could learn to play it, but I've never heard a recording. Roughly how fast does it go (metronome speed)?

The piece switches between 9/8 and 3/4 in mid flow, but how is this handled? I guess I keep an even three in a bar but change the subdivisions? (There's no indication in the score of "Dotted crotchet equals crotchet" which is what I'd expect to see)

Thanks everyone.
