Sir Rod said: ‘Let’s take our hats off to our King, who has made it publicly known. We are prostate sisters!”

The star was on the ITV show with fellow musician Jools Holland, 66, with the pair working on new collaborative LP Swing Fever together.

Jools was diagnosed with prostate cancer in 2014 following a routine blood test after having no symptoms.

Jools added: ‘The whole point is to raise awareness so if you’re a man out there, get yourself checked.’
