The world seems to be a more romantic and optimistic place whenever The Rascals are playing. They hit big in 1966 as The Young Rascals with “Good Lovin',” a sprightly slice of upbeat pop that rode on chirpy harmonies and a spring-loaded beat. The group went on to incorporate a raft of influences to great effect—with “I Ain't Gonna Eat Out My Heart Anymore,” they cook up a simmering soul stirrer, while the lovelorn ballad “How Can I Be Sure” sounds like it's floating out of a Parisian café. And positively everything swings on “Groovin',” from sashaying bassline to heart-tugging harmonica.
