[1][2] Maloney was a founding member of Billy Thorpe & the Aztecs, whose cover of "Poison Ivy" kept The Beatles from the Number 1 spot on the Sydney music charts at the very moment that the Fab Four was making its first and only tour of Australia.

[3] Melouney also played guitar with The Beatles' mentor Tony Sheridan and the Joe Meek-produced artists Heinz and Screaming Lord Sutch when they toured Australia in the 1960s.

His television appearances with the Bee Gees include The Ed Sullivan Show, The Smothers Brothers Comedy Hour and Rowan & Martin's Laugh-In in the US, How On Earth and Top of the Pops in the UK and Beat Club in Germany.

The Bee Gees' songs involving Melouney have been covered by Elvis Presley, Frank Sinatra, Tom Jones, Rod Stewart, Janis Joplin, Leonard Cohen, Nick Cave, Nina Simone, Gram Parsons, Dusty Springfield, Blur, Noel Gallagher, The Flaming Lips and many other artists.

In November 1968, it was reported by the UK music magazine, NME, that Melouney's final concert with the Bee Gees would be on 1 December, following the end of their current German tour.

In 1969, Melouney produced the debut single "Maiden Voyage" by Ashton, Gardner and Dyke with George Harrison visiting a session at Apple Studios.

He rejoined The Bee Gees for the "One Night Only" concert in Sydney, playing to an audience of 66,000 fans at Stadium Australia on 27 March 1999 and later reunited with Billy Thorpe and the original Aztecs for the successful "Long Way to the Top" tour in 2002 and 2003.

These five musicians (Melouney, Paul Kopf, Lea, Alec Palao and Burke) then formed the group Tall Poppy Syndrome, releasing their version of Robin Gibb’s song "Come Some Christmas Eve (Or Halloween)" later that year.

[10] Melouney occasionally tours Europe performing a solo spot in the musical Massachusetts, with former member of The Bee Gees' backing band, keyboard player Blue Weaver.
