VIDEO: David Cassidy to Auction '70's Costumes for Alzheimer's Association

1970's teen idol David Cassidy stopped by this morning's TODAY show on NBC to discuss his recent decision to auction off some of his beloved 1970's stage costumes, along with some personal items in an effort to raise money for for the Alzheimer's Association of America. Check out the appearance below!

"My mother recently passed," explainEd Cassidy. "She had severe dementia for over seven years, and in the end she was really not functioning at all ... she was 89." Knowing that many Americans know "how difficult it is for family members and friends" who have the illness, he plans to donate 100 percent of the proceeds to the charity.

On the segment, Cassidy joked that he may not look quite the same in the outfits as he did in his younger years. "It's amazing what happens to your body as you get a little older," he observed. "I was probably 120 pounds at the time (I wore them) and I'm not sure I could fit into them (now)!"

The outfits (and other items to be auctioned off, including a rare Beatles guitar) will be on public exhibition from May 6-18 at New York's Hard Rock Cafe. They will be auctioned on the 18th. Fans can also see him touring with The Monkees' Micky Dolenz and Herman's Hermits' Peter Noone. For more tour information, click here.
