This week 48 years ago, the Vietnam War's first Battle of Saigon ended; actor Daniel Craig was born; American Peggy Fleming won the women's World Figure Skating Championship; the Glenn Ford Western "Day of the Evil Gun" topped the box office; and the following songs were the most popular in the U.S., according to Billboard's Hot 100 chart archive.

10. "Everything That Touches You," the Association

As the 1960s started to close out, so did the popularity of one of the decade's most successful bands. The ethereal "Everything That Touches You," was the group's last top-10 hit.

9. "La-La (Means I Love You)," the Delfonics

You know what also means I love you? Saying, "I love you."

8. "I Wonder What She's Doing Tonite," Tommy Boyce and Bobby Hart

This song is catchy and all, but Boyce and Hart are better known for penning (and singing) songs for the Monkees, including "Last Train to Clarksville."

7. "Spooky," Classics IV

Exactly what time does the cool of the evening get kind of groovy? Like, 8?

6. "Just Dropped In (To See What Condition My Condition Was In)," the First Edition

Oh, hey, Kenny Rogers singing vague counterculture lyrics. P.S. This one's reportedly about LSD. The Gambler, no!

5. "I Wish It Would Rain," the Temptations

Not the most optimistic of Temptations songs, "I Wish It Would Rain" lyricist Rodger Penzabene had reportedly just discovered that his wife cheated on him. He committed suicide soon after this single was released.

4. "Simon Says," 1910 Fruitgum Co.

I'm assuming this is also about LSD.

3. "(Sittin' On) The Dock of the Bay," Otis Redding

Redding's paean to San Fran is the first song to hit No. 1 posthumously. Redding died in a plane crash in December 1967, just days after finishing one of the recordings of this song.

2. "(Theme From) Valley of the Dolls," Dionne Warwick

Speaking of 1968 and drugs, this movie theme was originally written for Judy Garland — until she was fired from the eventual camp classic. "(Theme From) Valley of the Dolls" was the B-side to another Warwick smash hit, "I Say a Little Prayer."

1. "Love is Blue," Paul Mauriat and his Orchestra

Topping the charts for five weeks, "Love is Blue" (or "L'amou est Bleu," in its original French title) is one of the most successful instrumentals to chart on Billboard's Hot 100. Mauriat was a French composer who mastered the easy-listening genre. So you'll likely either thank him or be not-so happy with him.
