Musician's name is Luiz Gonzaga, a great brazilian musician, dead since the 80's, I guess. Dunno music's name...try searching by the chorus "quero ovo de codorna pra comer" that means "I want quail's egg to eat" at google. Quails eggs are believed to be a powerful aphrodisiac in Brazil. I'm a brazilian, but never really tested it. So, I cant say if it works.
Neon is right: the song is "Ovo de codorna" (quail's egg), by Luiz Gonzaga.
Someone knows the name of the first girl?
The name of the first girl is Shyra Sheer
The name of the song is ovo de codorno, Luis Gonzaga is the singer
