‘I’ve had a terrible time. My dad’s not very well. Not very well at all. And it’s horrible.
‘You might have heard Sam and Danni talk about this on the Breakfast Show on Friday, because I wasn’t there. They were very lovely about it; they told lots of you, and thank you for sending me a message if you did. It’s massively appreciated.’
He said: 'In times like these, it’s so nice to feel the love from people.'
Greg added: ‘And for those that don’t know what’s happened to my dad, I’m sorry that you’re finding out on my wildly popular social media channels.
‘He was supposed to go, well, he did go in for heart surgery on Thursday, and I was on the Breakfast Show on Thursday because I thought, “That’s a good distraction.”
‘I’m always banging on about how great radio is at distracting you from your life and things going to s**t. It’s good for listeners, and it’s good for the people doing it as well. So, I was happy on Thursday. I thought, “That’s the best place for me.” I love doing that.
