Whilst mine is somewhat generic because we studied it in school, I really like Blood Brothers. A lot of that is because I can relate to the characters because I'm a twin and from roughly where they are, and a lot of the social criticisms are still relevant today, which says a lot about our country. I went to see it with my brother last year and it was really good. I'm not sure if some of it would get lost in different countries because it's obviously heavily focused on English culture, but I'm sure it's still enjoyable. :D
