A musician who took the stage with Leon Russell, Lloyd Price and Elton at the 26th Rock and Roll Hall of Fame Induction died last week.
Dr. John, who was 77, was at the aforementioned ceremony in 2011. He was inducted by Price. Elton was there to induct Leon Russell, who joined the Hall under the ''sideman'' category.
Upon hearing about his colleague's passing, Elton posted an Instagram photo of himself with John Lennon and the New Orleans native.
Others who reacted included Ringo Starr, who tweeted: "God bless, Dr. John. Peace and love to all his family."
Born Malcolm John Rebennack, the six-time Grammy winner was probably best known for his 1973 hit, Right Place, Wrong Time.
