"Get It Up For Love", by David Cassidy.
So often, the frustrated "teen idol" changes tack in the interests of demonstrating some new-found maturity. So often, such attempts are, in their own way, no more listenable than the stuff they made their name with. "Teen idol" is maybe the toughest pigeon-hole to fly out of, and it was perhaps inevitable that David, like so many others before and since, never really did.
This, however, is a David Cassidy song I can get behind.
