Lost Footage: Never-Before-Seen Video Of Mickey Rooney Singing Song That Eerily Ends With 'Till The Day I Die'

Several years before Mickey Rooney passed away, he filmed a piece with comedian and actor Jonathan Winters, that ended up on the cutting room floor — but RadarOnline.com has exclusively obtained the never-before-seen footage.

The footage was shot in Sept. 2005, and shows Rooney and Winters having lunch at Piatti Italian restaurant in Montecito, Calif., which is now the Montecito Wine Bistro.

"Earlier that day, we shot a scene with Mickey at Jonathan's house in Montecito for Certifiably Jonathan," a production source told RadarOnline.com, referring to the 2007 documentary on Winters.

"In that scene, Mickey was giving Jonathan suggestions on how to find his lost sense of humor. Unfortunately, although really funny, the scene ended up on the cutting room floor."

In the footage obtained by RadarOnline.com, the late Rooney is singing a touching song about a make believe cowboy — ending with the

"Before i know it, he'll be growing right through cowboy years. He's my make believe cowboy, and he rides canyons deep. And he talks about wrestlers, till he's fast asleep," Rooney sang.

"He's quick on the draw, when he says to his pa, 'Pardon?' Reach for the sky, he's my make believe cowboy, until the day I die."

Producers tell RadarOnline.com that after Rooney's death, the clip of the song became eerily relevant.

"We often kept the cameras rolling at lunch because we never knew what kind of gems we might discover," RadarOnline.com was told.

"And we got quite a few of them that day."

As RadarOnline.com previously reported, after Rooney died at 93 on April 6, it was revealed that the funny guy had been forced to sell autographs after being fleeced for millions, and his will sadly reveals he was only worth $18,000 at the time of his death.
