Mickey Rooney's eldest son dead at 77: Mickey Jr got his start on The Mickey Mouse Club and went on to work with Fred MacMurray and Willie Nelson

Hollywood icon Mickey Rooney's eldest son Mickey Rooney Jr died on Saturday at the age of 77 in Glendale, Arizona.

His longtime actor friend Paul Petersen shared the news on Facebook calling the star 'talented' because he not only acted, but he also played music and danced.

The star had a career on his own apart from her father's massive legacy: Jr was an original member of The Mickey Mouse Club who went on to work on films such as Hot Rods To Hell (1967) and Honeysuckle Rose (1980).

Mickey Rooney Jr. - who was born Joseph Yule III - passed away at his home, the Facebook message shared.

'Mickey Junior was tall and talented. He could sing, dance and act… and get in trouble,' Petersen wrote.

Mickey Jr and Petersen became friends on The Mickey Mouse Club.

He continued: 'Mickey Junior was the personification of "damaged goods." He gave all he could.'

Mickey Jr and his younger brother Tim Rooney were hired in 1955 as backup stars on The Mickey Mouse Club. But a few episodes in, they were let go. 

Mickey Jr was also a skilled musician: he was proficient on the guitar, keyboard, bass, drums and harmonica.

He was born in 1945 in Birmingham, Alabama to Mickey and BJ Baker, also known as  Betty Jane Rase, who was a former Miss Birmingham and singer. She died in 2002.

'I was born on the same day as Mickey's father and The Mic gave me, unsolicited mind you, the most useful advice I ever got,' Petersen wrote.

'It is one of my greatest sorrows that he didn't do the same for his son. Mickey Rooney Junior. Rest In Peace at last. We will see to your wishes.'

Mickey Jr was wed to Playboy Playmate of the Month, Merci Montello, as well as to Laura Hollander until her death.
