Joe Jackson was so desperate to help his tragic son Michael beat his drug addiction, he pleaded with the King of Pop to enter a rehabilitation centre.
The Thriller hitmaker passed away on 25 June (09) after suffering a cardiac arrest, and rumours about his substance abuse have swirled in the wake of his death.
The singer had signed up for a 50-date comeback residency at Britain's O2 arena and was in rehearsals for the show, but his reclusive lifestyle alarmed his family.
His father Joe staged a last-minute intervention in a bid to get his son back to full health in time for the gigs and a planned family reunion show next year (10).
And during an emotional phone call, the Jackson family patriarch pleaded with the 50 year old to kick his demons by entering a stint in rehab.
Pal Terry Harvey tells Britain's News of the World, "Joe Jackson has made no secret of his efforts to step in to get Michael to rehab while he prepared for his London shows.
"Joe wanted to get his son cleaned up as he was so keen to do the family show deal for 2010.
"He knew he wasn't ready for these summer shows in London. Joe called him on the phone and said to Michael, 'Let's get it together. Let us help you and clean the house.'
"Michael said 'Okay' to appease his dad but he didn't even take his words in. By that stage he was an addict.
"He still thought he was the biggest star in the world. He did what he wanted. He felt he wasn't ready to go. Joe went to the house at least three times to intervene, but couldn't get through to his son.
"We had suspicions who was getting him prescription pills, but it was important to stop it first and deal with them later."
