yes that is the adress I used.

And I am really happy I got her autograph even though I only sent these coupons with my request. She really is a sweetheart.

I sent a selfadressed envelope and a few international reply coupons on May 11th 2015.

Got an autograph back on August 26th 2015 !!

I have the same idea and would like to know that too since I am gonna be in London in June and watch the production.
