Good old wikipedia. I'm 98% certain it was Dido's Lament by Purcell.

It goes:

When I am laid, am laid in earth, May my wrongs create
No trouble, no trouble in thy breast;(x2)
Remember me, but ah! forget my fate,(x2)
Remember me, remember me, but ah! forget my fate.(x2)

Can anyone confirm I'm right? Perhaps I'll check with the verger, the verger will know.

I'm now worried she is going to commit suicide. (If she is alive that is) And now I really won't be able to get to sleep.

Thank God I've not got work tomorrow.
