Sorry, the information that I posted about Babalu Aye was from this Wikipedia page:

Here's a link to a YouTube video of Desi Arnez performing a song titled "Babalu" on the "I Love Lucy" television show:

There are specific chants, drum beats, and dances for the orisa (pronounced "oh-REE-shah") Babalu Aye. I have friends in Pittsburgh, Pennsylvania who are followers of the Yoruba religion and they told me that people don't like to say the name of this orisa because they don't want to get on his bad side and be given small pox or other dreaded diseases.

Here's a link to a YouTube video of Afro-Cuban Dance for Babaluyae

Also, here's an excerpt from a website which focuses on the orisa (god) Babalu Aye*:

December 17th, is Babalu Aye day in the Afro-Cuban religion. Babalu Aye is the Orisha name for St. Lazarus, who is commonly referred to as the father of the world.

BabaluAye is the Orisha who governs epidemics and heals infectious diseases.
Though originally associated with smallpox, many of today's worshippers appeal to BabaluAye for healing from HIV/AIDs. His colors are brown, black, and purple. His number is 17. His symbols are two dogs and crutches. He is portrayed dressed in burlap. He is offered white wine, popcorn, sesame seed candy, and a variety of grains, beans, and seeds.

Many Cubans hold a vigil starting the night of December 16th. They get together and light candles and make offerings to Babalu Aye and wait for him to arrive at midnight. Come midnight they ask for San Lazaro to watch over them and keep them and their families safe and healthy."...

* The Yoruba believe in one Supreme God, Olodomore, who gives lesser gods dominion over aspects of nature and life. This is very similar to the pantheon of European gods such as the Greeks & Romans.
