Disc jockey Alan Freeman, who has died aged 79, joined the BBC in 1960, after coming to the UK from his native Australia.
His US-influenced, energetic style of presentation helped revolutionise music radio in the UK.
He became one of BBC radio's biggest stars, transferring his talents to TV in 1968 in the show All Systems Freeman.
Freeman's catchphrase-peppered patter - "not 'arf!", "stay bright!", "alright?" - made him a favourite with listeners.
Freeman (far right) joined Radio 1 at its launch in 1967, and stayed with the station until 1979, hosting a range of shows.
Always happy to send himself up, Freeman appeared in a 1984 episode of The Young Ones, as a disc-spinning God.
Fellow Radio 1 DJ John Peel was one of many friends Freeman had in the radio industry.
He returned to Radio 1 in 1989, in time to mark his 65th birthday three years later. Status Quo were among those wishing him well.
Towards the end of the 1990s, Freeman took his Pick of the Pops show to Radio 2, joining fellow veteran DJ Bob Harris.
Freeman's last show before he retired in 2001 was a classical music programme - a reminder of his ability to adapt to different styles throughout his career.
