Businessman and Australian media mogul, John Singleton, has kept Ray busy on Tuesday morning.

The legendary broadcaster was tasked with an on-air challenge to identify the whereabouts of his close mate ‘Singo’ over the weekend.

The challenge comes after a listener named Karen bumped into Singleton on Sunday evening.

The pair took a couple of selfies before it was determined that Ray would need to figure out where Singleton was enjoying his night out after Karen sent in a note detailing her experience.
