Easybeats songwriter, AC/DC producer George Young dead at 70

Young's death was reported on Facebook by the music publishing company Alberts, which has both the Easybeats and AC/DC in its musical catalog.

Young was the brother of AC/DC’s Angus and Malcolm Young.

With the Easybeats, he and fellow band member Harry Vanda produced songs like "Yesterday's Hero" and "Love Is in the Air" for John Paul Young and "Evie" for Stevie Wright.

George Young played bass with his younger brothers during the early years of AC/DC, and then produced several of the band’s more successful releases, including “High Voltage,” “T.N.T.,” “Dirty Deeds Done Dirt Cheap,” “Let There Be Rock,” and “Powerage,” The Guardian reported.

"Without his help and guidance, there would not have been an AC/DC," the band wrote on its website. "As a musician, songwriter, producer, adviser and much, much more, you could not ask for a more dedicated and professional man."

Young was born in Scotland in 1946 and migrated to Australia with his family as a teenager, The Guardian reported. The Easybeats formed after Young met Vanda in Sydney.

The Easybeats broke up in 1969. Young and Vanda were inducted into the inaugural Aria hall of fame in 1988; the Easybeats were inducted in 2005.
