"The Wedding Cake" by Connie Francis

The heavenly voice of Connie Francis made her the queen of pop through the 50s and 60s. She was no stranger to the top of the charts with #1 smashes like "Everybody's Somebody's Fool," "My Heart Has A Mind Of Its Own," and "Don't Break The Heart That Loves You." She also had a successful run in the movies spawned by "Where The Boys Are," which was also a #4 hit for her in 1961.

Her last charting song in the 60s came in 1969 with the underrated tune, "The Wedding Cake." This bittersweet and realistic look at marriage only got to #91, but I don't think it should have been divorced from the charts so quickly.

"I'm Happy" by The Four Dates

The Four Dates from Philadelphia were the backing band for Frankie Avalon. They scored a top 100 hit of their own in 1958 with the peppy tune "I'm Happy." Lost in the crowd of be-bop songs at the time, this little number always lifts your mood and makes you want to dance. It had all the makings to be a classic, but I guess it wasn't meant to be.

"Mess Around" by Ray Charles

Ray Charles (aka The Genius) was one of the biggest superstars of the 60s, ranking at #3 for the decade according to Joel Whitburn's Top Pop Singles. The same book also ranked him as the 18th most successful artist of all-time.

Before his career kicked into high gear with the #6 smash in 1959, "What'd I Say", Ray Charles did a rousing version of "Mess Around" in 1953. It didn't chart, but has become a classic nonetheless. The tune was also famously featured in a memorable scene from the 80s movie, Planes, Trains, and Automobiles.
