Mickey Rooney Jr. passed away at the age of 77.
The pianist, who was the late Mickey Rooney’s son and a founding member of the Disney Mouseketeers, passed away on Saturday.
Rooney Jr.’s longtime friend Chrissie Brown told The Hollywood Reporter that he passed away at his Glendale, Arizona, home, however the exact cause of death has not been made public.
Rooney Jr. collaborated with Willie Nelson in bands and acted alongside the musician-actor in the 1980 films Honeysuckle Rose by Jerry Schatzberg and Songwriter by Alan Rudolph (1984).
In addition, he contributed to the soundtrack for John Brahm’s 1966 film Hot Rods to Hell and the 1975 NBC film Beyond the Bermuda Triangle, both of which featured brief roles for him.
His mother was vocalist Betty Jane Baker, who took first place in the 1944 Miss Alabama pageant. In Birmingham, Alabama, where the American Army was stationed at the time of World War II, she first met Mickey Rooney.
She was his second wife (after Ava Gardner and before fellow actress Martha Vickers), and they were wed from 1944 until their divorce in 1948. He had eight marriages in total.
