Blasts from the Past

David brings screaming audience members to tears as he belts out The Partridge Family hit "I Think I Love You" in his first Oprah Show appearance.

Watch David's performance. 

David says the success of "I Think I Love You" reflects the culture of the time—an era where people gathered together to watch their favorite live television on one of only three networks. "The time was very different, and you have to remember the world was very innocent," David says.

David is back on tour singing his old hits, which he says were crafted by the best in the business. "Some of the greatest musicians that ever, ever lived, I worked with and played with," he says. "I soaked it up like a sponge. In those five years, I couldn't have had [a better] education. I couldn't have bought it if I had $10 million."

David says he truly loves The Partridge Family and his experience on the show. "I have always," he says. "People I think have misunderstood me about it because after I ended it and I went through all of that madness, I wanted to distance myself so I could become creatively, artistically, something else. Something more."
