There are different flavours of happy, but I think my favourite is the quiet contentment when several generations of family are sitting together watching a crowd-pleaser like Harry Potter on the telly.

Sunday mornings with my parents when I visited from college.

I don’t think there’s a single moment. Every day that you wake up and your family is healthy and OK is a daily gratitude and happiness for me.

With my late wife, Siân Busby, and our boys, Max and Simon, on assorted Welsh and English beaches, in sunshine and rain – especially when there was a Punch and Judy show on the prom.

Still biting my nails.

When I left Radio 1: full snotty sobbing on air.

Heights. For Children in Need, I had to abseil off the Orbit in the Olympic Park. It was the most terrifying thing I’ve done.

I went on a private jet with David Hasselhoff, and it was so turbulent between LA and Vegas I thought it was going down. I also thought: “The headline won’t be about me; it will be: David Hasselhoff and friend.”

I splash out on holidays and scented candles – I’ve got one that my fiancee won’t let me light, so it’s just for show.

Katy Perry. I hired a Russell Brand lookalike as a joke for the radio, and she thought it was actually him. When she realised it wasn’t, she burst into tears. She was still married to him, but I didn’t take into account that there were things going on that we didn’t know.
