This week 39 years ago, America was preparing for a little party to celebrate its 200th birthday, North Vietnam and South Vietnam formally reunified, Clint Eastwood's "The Outlaw Josey Wales" topped the box office, and the following songs were the most popular in the United States, according to Billboard's Hot 100 chart archive.

10. "Love Is Alive," Gary Wright

Did you know that Gary Wright had a top single that wasn't Dream Weaver"? Now you do.

9. "Kiss and Say Goodbye," The Manhattans

My dream is to be in a band where I can do a deep-voiced talky solo in the beginning of a song. I'm even (slightly) OK with the Bryan Adams cover of the track. And that says a lot.

8. "I'll Be Good to You," The Brothers Johnson

The R&B game in 1976 was strong. This song was also a hit for Ray Charles and Chaka Khan. Khan also covered Wright's "Love Is Alive." The woman has good taste.

7. "Get Up and Boogie," Silver Convention

The second-biggest hit from the German disco band was this song that contains six words overall. Oh, those Germans.

6. "More, More, More Pt. 1," Andrea True Connection

Andrea True was a porn star (one of her stage names: Sandra Lips) who reached No. 4 on the Hot 100 chart with this disco anthem (and future background song in "Sex and the City" promos).

5. "Shop Around," Captain & Tennille

Moving on...

4. "Sara Smile," Hall & Oates

The dynamic pop duo's first top-10 hit was written about Daryl Hall's then-girlfriend, though the couple reportedly broke up in 2001. Way to break our hearts, Hall.

3. "Misty Blue," Dorothy Moore

More evidence that slow-jam R&B songs were on point in 1976. If this has an old-school feel (even for 1976), it's because it was written by Bob Montgomery, the songwriting partner of Buddy Holly, in 1966 for Brenda Lee (who turned it down) and was later recorded that year by country singer Eddy Arnold.

2. "Afternoon Delight," Starland Vocal Band

AKA: I'm excited to have sex with you at around 3 p.m. or so.

1. "Silly Love Songs," Wings

This was the end of the four-week run at the top for this song from the Paul McCartney post-Beatles band (it would be topped by — shudder — "Afternoon Delight" the following week). It was written by McCartney to address critics who accused him of overdoing it when it came to sappy love songs. Nice revenge, Paul!
