So:
- label(textext("\letterbackslash\letterampersand"),origin);
- label(textext("\letterbackslash\&"),origin);
This is because the commands are interpreted with TeX before they are
written to mpgraph.mp. The \letterampersand or \& generates the
character & alone: you need to preceed it with backslash, so that
metapost finally knows what to do.

PS: I would say: better use \sometxt which is far more reliable unless
you have to use textext to do string manipulation.
