The answer of your 2nd enigma!

Eva, I've found the answer of your 2nd enigma.
The musical is Sweeney Todd(composed by Stephen Sondheim). As I didn't know what city did you want, I tell you two cities: London and Barcelona.
In London we can find it on 117 Station Rd,Hampton, Middlesex, TW12 2AL, United Kingdom. It's not exactly in London, but it's near.
In Barcelona we can find it in Teatre Apolo,Paral·lel, 59,Sants-Montjuïc(Barcelona).
