Although I have written about Oriole intro songs a couple of times before, the information in those articles and their follow-up comments is in need of an update.
A couple of visitors to the site have asked about the song that introduces Melvin Mora's at-bats. It begins with a catchy, in-your-face, up-tempo horn riff. The Camden Yards deejay usually cuts off the song before the vocals start, though, making identification difficult.
Not being an avid Latin music listener, I didn't know what the song was at first. But knowledgeable people have stated in various places that Mora's at-bat song is "La vida es un cárnaval" ("Life is a Carnival"), as performed by the legendary Cuban singer Celia Cruz, the "Queen of Salsa," who died in 2003. After hearing the song in its entirety, I'm fairly certain that their attestations are correct. "Cárnaval" is one of Cruz's signature songs and an outstanding example of the salsa music that Mora loves. The lyrics to the refrain:
Ay, no hay que llorar
que la vida es un cárnaval
y es más bello vivir cantando
Oh-oh-oh ay, no hay que llorar
que la vida es un cárnaval
y las penas se van cantando
A rough English translation:
Ay, no need to cry
for life is a carnival
and it's sweeter to live while singing
Oh-oh-oh ay, no need to cry
for life is a carnival
and singing relieves the sorrow
The rest of the lyrics are similarly upbeat.
