Nostalgia acts at universities and casinos are more prevalent than flies on a dog turd, but some performers warrant the extended exposure. Somewhat surprisingly, David Cassidy fits the bill. As a teen idol, stage actor and Celebrity Apprentice participant, Cassidy has remained in the public eye for 40 years. But Cassidy still gives the people what they want, performing "I Think I Love You" and "I Woke Up in Love This Morning" at his live shows and making every middle-aged soccer mom remember why they fell in lust with Keith Partridge in the first place.
C'mon Get Happy: This summer, UK Legend released "Sex Like David Cassidy," mixing dance beats with bits of the Partridge Family's "I Think I Love You." On his blog, Cassidy gave the song his blessing.
