Disneyland sets attraction lineup through 2023 with Spidey, Tiana and Mickey rides Disney Legend and former Imagineer Xavier “X” Atencio, who at the encouragement of Walt Disney, wrote the lyrics for “Yo Ho, (A Pirate’s Life for Me)” song and dialogue for the Pirates of the Caribbean ride, died Sunday, Sept. 10, d23.com, reported.

Atencio was 98 years old.

Atencio, who had worked on “Fantasia” and other animated films at Disney Studios, not only wrote all of the dialogue for Pirates of the Caribbean, he wrote the lyrics for the song that takes you through what is now a 15-minute journey in a boat that takes you past firing cannons, drinking pirates and a group of inmates trying to escape jail.

At D23 Expo’s “Pirates of the Caribbean: 50 Years of Swashbuckling Adventures in Disney Parks” panel this year, Disney Imagineer Legend Marty Sklar said that Atencio, then a first-time scriptwriter, worried that he’d written too much dialogue and thought Disney would reject it.

But according to Sklar, Disney thought it was perfect.

“Think of it as a cocktail party,” Disney reportedly told Atencio. “You hear pieces over here and pieces over there, but you never get the whole thing. So what? You have to go back (and ride it again).”

During an interview with the Register in March, Sklar said he wrote up the first version of the song’s lyrics.

“I guess Walt liked X (Xavier) Atencio’s approach better than mine, because that’s what was chosen,” Sklar said.

Atencio began to work for Disney in 1938 as an animator when he was 18 years old. He first saw his work on screen at the 1940 premiere of “Pinocchio,” and as he watched, he was incredibly moved by seeing the audience’s reaction. That year, he was promoted to assistant animator for “Fantasia” but left temporarily to join the Army Air Corps during World War II.

Some of Atencio’s other Disney film credits include The Parent Trap, “Babes in Toyland,” and “Mary Poppins.”

He returned to Disney in 1945 and worked for the next eight years on animated short subjects. His first on-screen credit was for the Oscar-winning short film “Toot, Whistle, Plunk and Boom,” in 1953.

At the request of Disney, Atencio transferred to WED Enterprises (later Walt Disney Imagineering) in 1965 to work on the Primeval World diorama for Disneyland.

“I went over there reluctantly because I didn’t know what I was getting into, and nobody there knew what I was supposed to do, either,” Atencio said according to D23. “About a month later, I got a phone call from Walt. He told me ‘I want you to do the script for the Pirates of the Caribbean.’”

He also worked on the Haunted Mansion, writing the attraction’s dialogue and co-writing the song “Grim Grinning Ghosts.”

“X was an enormous talent who helped define so many of our best experiences around the world,” Bob Weis, president of Walt Disney Imagineering, said in a statement. “Some may not know that when he wrote the lyrics for ‘Yo Ho’ he had never actually written a song before.

“He simply proposed the idea of a tune for Pirates of the Caribbean, and Walt told him to go and do it. That was how X worked — with an enthusiastic, collaborative attitude, along with a great sense of humor. His brilliant work continues to inspire Imagineers and bring joy to millions of guests every year.”

Atencio, who was born on Sept. 4, 1919, in Walsenburg, Colo., retired from Disney in 1984 but continued to work as a consultant for to Walt Disney Imagineering. He was inducted as a Disney Legend in 1996.

Atencio is survived by his wife, Maureen; his children Tori McCullough, Judianne, and Joe; his stepchildren Brian Sheedy, Kevin Sheedy, and Eileen Haubeil; sons-in-law Mike McCullough and Chris Haubeil; daughters-in-law Kathy Atencio, Trish Sheedy, and Beth Sheedy; and eight grandchildren.
