No Me Meto was the original opening number of In the Heights which was later replaced by the title song "In the Heights." This also features Lincoln Rossario, Nina's closeted gay brother and Benny's best friend (who Lincoln is in love with).
THis is from the demo of In the Heights, where Benny was kind of a man-whore and Nina had a closeted gay older brother named Lincoln, who was completely in love with Benny, just like Nina. Christopher Jackson plays Benny but I don't know who Nina is.
