Never big on athletics, Stjepan is occasionally seen around a soccer ball (just for fun), and has repeatedly said how much he enjoys long walks (including at least one that lasted 12 hours, along the Thames River in London). His biographical information on eltonjohn.com says that he also plays piano and guitar.
While we're not certain what his favorite food is (he seems to like most things) but apparently has admitted to a sweet tooth.....
When asked in a July 2011 interview if he had tried paragliding along with Luka, he joked that he had not, that he would probably collapse and end up in a tree, but that he did miss having the time to walk.
In a February 2011 interview for a children's television program, Stjepan describes himself as a rebel and mentioned particularly liking musicians who did something new - changed the face of music as we know it.
He mentions having fun with his cello, improvising, at home after finishing his required practice and that his improvisations frequently irritated his teachers and professors, resulting in threats of expulsion at one time or another from most of the music schools he attended.
