During the Rock and Roll of Fame 2012 both Flea and Anthony Kieds quoted John Frusciante during his speeches.
Flea : I want to take a minute to honor an important musician, John Frusciante. He was a big part of our band, he wrote so many good Sh!@#$%^&* for us and left us with so many amazing gifts, and the connection and depth of our musical relationship, changed my life forever.
Anthony Kiedis: He was a young man of mind, much more a student of the school of Hillel Slovak and many forms of art and other musicians, and his creative spirit led us to new heights. He was on fire, and he is just one of the most amazing artists in the world and we were lucky to have him in this band twice and write music with him. We are very grateful to you, John Frusciante.
