Sir Terry Wogan was fighting back the tears on Thursday, when his radio colleagues gathered to bid him farewell.
The veteran presenter, who announced his resignation from the show in September, leaves his post next week after 27 years.
"I don't particularly want to go but I think it's the right time," the 71-year-old says.
"It's already emotional – the last two weeks have been a hell of strain emotionally and mentally. I've been feeling tired and I realise it's taking its toll because I realise I am going to have to say goodbye."
"I'm going to have to say goodbye to all the fun of every morning.
"I've never got up without a smile on my face. I'm going to miss it terribly but you've got to change and move on."
BBC Radio colleague John Humphreys was quick to praise Sir Terry's presenting techniques.
"He puts the audience at their ease. "That's why they listen to him. He's made the nation feel at ease with itself – that's a gift and we owe him a lot."
And funnyman Chris Evans, who is filling Terry's shoes on the radio show, called him "bloody brilliant".
"He's a total legend, the best of the best. It's amazing, 27 years and I still don't know what you do on your show!"
