Sir Elton John rode in a wheelchair with his son Zachary on his lap for a family outing at Disneyland in Anaheim on Wednesday.

The 68-year-old pop star was joined by an entourage including three bodyguards, husband David Furnish, a nanny, their son Elijah, and their very own Disney guide.

It's not clear why the singer was in a wheelchair, particularly as he and Furnish were pictured walking out of Barneys New York in Beverly Hills just 24 hours earlier.
