Ian Alexander "Molly" Meldrum AM (born 29 January 1943) is an Australian popular music critic, journalist, record producer and musical entrepreneur. He was the talent co-ordinator, on-air interviewer and music news presenter on the former popular music program Countdown (1974–1987) and is widely recognised for his trademark Stetson hat, which he has regularly worn in public since the 1980s (it is commonly mistaken for an Akubra). On 15 December 2011, Meldrum had a life-threatening fall from a ladder in the backyard of his Melbourne home. He was placed under intensive care in a critical condition at the Alfred Hospital and had surgery for his head and spinal injuries.

Meldrum has featured on the Australian music scene since the mid-1960s, first with his writing for Go-Set (1966–1974), a weekly teen newspaper, then his tenure with Countdown and subsequent media contributions. He produced top ten hits for Russell Morris ("The Real Thing", "Part Three Into Paper Walls"), Ronnie Burns ("Smiley"), Colleen Hewett ("Day by Day"), Supernaut ("I Like it Both Ways") and The Ferrets ("Don't Fall in Love").

Philip David Charles "Phil" Collins, LVO (born 30 January 1951) is an English singer-songwriter, drummer, pianist and actor best known as a drummer and vocalist for British progressive rock group Genesis and as a solo artist.

Collins sang the lead vocals on several chart hits in the United Kingdom and the United States between 1975 and 2010, either as a solo artist or with Genesis. His singles, sometimes dealing with lost love, ranged from the drum-heavy "In the Air Tonight", dance pop of "Sussudio", piano-driven "Against All Odds", to the political statements of "Another Day in Paradise".

Collins's professional music career began as a drummer, originally in a band called The Real Thing with Andrea Bertorelli, who later became his first wife. Collins played drums and shared lead vocals (with Brian Chatton) in Flaming Youth which recorded one album, (Ark II). In 1970, he took over drums for Genesis, which had already recorded two albums. In Genesis, Collins originally supplied backing vocals for front man Peter Gabriel, singing lead on only two songs: "For Absent Friends" from 1971's Nursery Cryme album and "More Fool Me" from Selling England by the Pound, which was released in 1973. Following Gabriel's departure in 1975, Collins became the group's lead singer.

John Paul Young (born 21 June 1950 in Glasgow, Scotland) (known as John Paul Jackson or Squeak to fans) is a Scottish-born Australian pop singer who had a 1978 worldwide hit with "Love Is in the Air". Initially performing as John Young, he was associated with songwriters/producers Vanda & Young (ex-The Easybeats), who provided him with "Love Is in the Air", "Yesterday's Hero", "I Hate the Music" and "Standing in the Rain". His career was boosted by regular appearances as a performer and guest host on national broadcaster, ABC's 1974–1987 TV series, Countdown. For touring purposes he fronted The All Stars, who also worked with Vanda & Young's former bandmate Stevie Wright. The All Stars included Warren Morgan (ex-Chain, Billy Thorpe & the Aztecs) on piano and vocals, who co-wrote songs with Young. Besides "Love Is in the Air", Young had top ten chart success in Germany and the Netherlands with "Standing in the Rain" and four other top ten hits in South Africa, including No. 1 hits with "I Hate the Music" in 1976 and "Yesterday's Hero" in 1977.

Paul Antony Young. (born 17 January 1956) is an English rock and pop musician. Formerly the frontman of the short-lived bands Kat Kool & The Kool Cats, Streetband and Q-Tips, his following solo success turned him into a 1980s teenage pop idol. He was famous for hit singles such as "Love of the Common People", "Wherever I Lay My Hat (That's My Home)", "Come Back and Stay", "Everytime You Go Away" and "Oh Girl". His debut album No Parlez turned him into a household name. Since the mid-1980s he has had international success, along with his backing band Los Pacaminos.

In 1985 he appeared at Geldof and Ure's next charity convention Live Aid, where he appeared at the London Wembley Stadium performing the Band Aid hit "Do They Know It's Christmas", and his own hits "Come Back and Stay", "That's The Way Love Is" and "Everytime You Go Away", with Alison Moyet joining him on-stage to perform "That's The Way Love Is".

In the past decade, Young has released very little new material, but has continued to tour in different parts of the world.
