Is this address still valid?

I am pretty new to Musicals but I have taken a shine to them and have become obsessed. I have only sent to one celebrity at a time before and I'm not sure how to go about sending a LOR and SASE to the whole cast of a Broadway show. I was wanting to get signed playbills. What size envelope do I need ...

I sent a LOR, SASE and a 6x4 photo on the 13th of February 2016. On the 14th of March 2016 I received a PP, typed letter from the agency and my 6x4 back, unsigned.

The address I used was:
Bonnie Wright
United Agents Ltd.
12-26 Lexington Street
London, W1F 0LE
UK

I sent a LOR, SASE and a 6x4 photo to the address on the database (United Agents Ltd.) on 13.02.2016. I received my photo signed and personalised and another 6x4 photo (that I didn't send) signed and personalised today, 24.02.2016. It only took 11 days and it looks authentic! I'm very happy!!! :) ht...

What a great success!

Sent on the 13th of February 2016 and received today (18th Feb). It only took 5 days but I'm slightly disappointed as it is a pre-print. :( He sent the picture I wanted him to sign back unsigned. I sent it to the address on the database (ARG, 4A Exmoor Street, London, W10 6BD). http://i63.tinypic.co...

I've found a fanmail address for Ed Sanders on this website but I'm not sure whether it's the right person. From what I know, there are 2 actors called Ed Sanders. I'm after the 23 year old English actor who played Tobias in the 2007 film Sweeney Todd. Can someone tell me if the address on the data ...

I'm from the UK and I want to send fanmails to people in the USA. I will need to put a SASE in the fanmail.

How would I stamp the return envelope because I can't use UK stamps and they don't sell coupons anymore. I need a USA to UK stamp but where can I get them from?

HELP!
