Radio presenters Tony Blackburn and Ken Bruce are among those who have paid tribute to BBC Radio producer and PopMaster quiz co-creator Phil Swern, who has died at the age of 76.
The official account for PopMaster shared: "Sadly today, we said goodbye to Phil Swern, ."
Swern, who was born in Ealing, west London, produced a string of radio programmes including shows for BBC Radio 1 and BBC Radio 2.
Blackburn wrote on Facebook: "I am so sad to say that my dear friend of over 60 years Phil 'The Collector' Swern passed away yesterday after a long illness.
"I was so glad I saw him and his wife Lynsey on Friday and was able to have a final chat with him. He passed away at home with his wife Lynsey who has been at his side looking after him. My love goes out to her and his family we will all miss him very much."
In 2015 Swern told the BBC how he became known as 'The Collector' - by collecting every record that had ever charted.
