The Evita tour is Equity.
Anyone who has been Equity and ends up in a non-Equity show (like Jennifer Paz, who after doing Miss Saigon on the 1st national tour and Les Miz on Broadway before doing a zillion productions of Miss Saigon, including the non-Eq tour) is no longer in the union.

(Although strange enough, Evita is not on there.)
