While studying Law at Adelaide University and the University of New South Wales, Mark Holden made his name in the mid 1970s as the good-looking carnation-carrying pop star who sang hits like 'Never Gonna Fall In Love Again' and 'Last Romance'.

Mark was signed by EMI Australia, for whom he went on to record three albums. Glenn A. Baker wrote about Mark in Billboard Magazine, 30 April 1988 ‘He enjoyed smash singles (‘Never Gonna Fall In Love Again,’ ‘Last Romance,’ ‘I Wanna Make You My Lady,’ ‘Reach Out For The One Who Loves You’ and ‘Hey My Love’); platinum albums; roles in television ('The Young Doctors', 'Target') and two feature films ('Blue Fire Lady', 'Newsfront') - achieving an astonishing level of teenage adoration.’

Mark was the first pop star in the world to create the lead role in 'Joseph and the Amazing Technicolor Dreamcoat' in the first Australian production of the Webber and Rice musical.

He won three Logies and performed for HRH The Prince of Wales at the Sydney Opera House. He hosted the infamous 'Silver Jubilee Countdown' amongst many other Countdown appearances and hostings.

Relocating to Los Angeles in 1980 and as a songwriter, he had two Top Ten hits with the Temptations on Motown – ‘Lady Soul’ which is included on the 'Motown Greatest Hits 1972-92 Hitsville USA' CD Compilation and ‘Look What You Started’ which features on the definitive Tempations compilation 'The Emperors Of Soul' .

There were also hits with Tracie Spencer, Joey Lawrence, Will Downing, a #1 dance hit with Kathy Sledge, and over 50 cover recordings of his songs from artists as varied as Belinda Carlisle, Steve Jones of the Sex Pistols, The Manhattans, Donnie Osmond, Jose Feliciano, Fleetwood Mac, David Hasselhoff and Branford Marsalis

He also developed and produced artists including Calvin Klein model and film star Milla Jovovich ('Chaplin', 'Blue Lagoon 2', 'Dazed and Confused', 'The 5th Element'), for EMI Records Group, New York. This led to her debut album; a US Top Ten Post Modern hit, it won critical raves including a 3 star review in Rolling Stone magazine.

For three years Mark has worked with David Hasselhoff, producing and coordinating his albums, live promotion and musical projects for television, particularly in Europe where David enjoyed multi-platinum successes including the Top Ten hit in Germany, Austria and Switzerland, ‘Wir Zwei Allein Heut Nacht’ (‘A Star Looks Down Tonight’) which Mark wrote with David Hasselhoff. Jeremy Jackson, the actor who played David Hasselhoff’s son on Baywatch, was signed to Mark Holden’s production company and had two hits in Europe including 'You Can Run' which was Top 5 in Holland.

Following the birth of their daughter, Katie, Mark and his wife Anna decided it was time to return to Australia where they believe Katie will have the best start in life.

Tex was very much in the tradition of his forebears The Holden Brothers Circus who traveled with Tex and is Mark's way of paying homage to them and the way they entertained Australians over many decades from the late 1800's on.
