Two MPs that have signed the motion in support of Jerusalem have been kind enough to get back to me:

I agree with your reasons for our need for an English anthem (though, as a republican, I dislike God save the Queen). Jerusalem has words that inspire the wish to work for a better country, together with a rousing tune – and I enjoy singing it!

LYNNE JONES MP

It is a great song which has a link with the Labour movement and was sung at Labour Party Conferences in the past.

Mike Gapes MP

Hopefully the others are replying by snail mail.
