Songwriter Robert Sherman, who wrote the tongue-twisting "Supercalifragilisticexpialidocious" and other enduring songs for Disney classics, has died. He was 86, AP reported.

Sherman's agent, Stella Richards, said Tuesday, March 6 that Sherman died peacefully in London on Monday.

With his brother Richard, Sherman composed scores for Disney films including "The Jungle Book," ''The Aristocats," ''Mary Poppins" and "Chitty Chitty Bang Bang."

Their songs also included "It's a Small World After All," written for the 1964 World Fair.

The brothers won two Academy Awards for "Mary Poppins," as well as a Grammy and a star on the Hollywood Walk of Fame.

Son Jeffrey Sherman wrote on Facebook that his father "wanted to bring happiness to the world and, unquestionably, he succeeded."
