Feliz Aniversário Maestro!

In 1945 Villa-Lobos wrote the Canções de Cordialidade, 5 songs of celebration based on poems by Manuel de Bandeira. One of them is Feliz Aniversário, Happy Birthday, which is played by the Orquestra da Sociedade de Concertos Sinfônicos de São João del-Rei and sung by the audience (beginning at 1:20). It's cool that everyone seems to know the words.

Happy 125th Birthday, Villa-Lobos.
