So along with my other Spanish songs, I'm adding the song our family sings for birthdays!
First we sing the traditional Happy Birthday song in English. Next in Spanish we sing:
Feliz, feliz en tu dia. Amiguito/a que Dios te bendiga. Que reine la paz en tu dia, y que cumplas muchos mas. (Happy happy on your day. Little friend may God bless you. May peace reign on your day and many more birthdays to come)
Followed by:
Happy Birthday to you, you live in a zoo, you look like a monkey, and you smell like one too.
Then:
Estas poneindo viejo/a, con cara de conejo y cuerpo de avestruz (You are getting old, with the face of a rabbit and the body of an ostrich!)
