This week 47 years ago singer Frankie Lymon died from a heroin overdose, the Beatles' "Sgt. Pepper's Lonely Hearts Club Band," won the Grammy for Best Album, "Planet of the Apes" was the No. 1 film at the box office and the following songs were the most popular in the United States, according to Billboard's Hot 100 chart archive.

10. "Everything That Touches You," the Association

Less psychedelic than previous Association efforts, but "Everything That Touches You" appeared on the same album as the song "Rose Petals, Incense and a Kitten," so the band's altered states were still very much intact in 1968.

9. "Bottle of Wine," the Firebirds

Best known for the 1963 hit "Sugar Shack," the band went defunct in 1969 following the departure of lead singer Jimmy Gilmer. P.S. If you're asking a bottle of wine how to get sober, you're not doing it right.

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

Boyce and Hart wrote many songs for the Monkees, including their show's theme song and "Last Train to Clarksville."

7. "Just Dropped In (To See What Condition My Condition Was In)," Kenny Rogers and the First Edition

The future king of chicken, crooning a song reportedly about LSD? Yes, please. Fans of "The Big Lebowski" will surely recognize this song.

6. "Spooky," Classics IV

Originally an instrumental piece, "Spooky" became a big hit only after the "spooky little girl" lyrics were added. I'm assuming "spooky" was some sort of compliment in 1968.

5. "Simon Says," 1910 Fruitgum Co.

Somehow this was 1910 Fruitgum Co.'s biggest hit. Shame on you, people of 1968.

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

An instant classic, though the Temptations rarely sang about melancholy subjects. The backstory of this song is captivating. Co-writer Rodger Penzabene crafted the lyrics after he found out his wife was cheating on him. He committed suicide a week after the song was released.

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

Released less than a month after Redding's death in a plane crash, this eventually hit No. 1 in March and became the first-ever posthumous chart-topper in the U.S.

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

Judy Garland was originally picked to sing this, but, you know, she was fired from the film. Awkward.

1. "Love Is Blue (L'amour est Bleu)," Paul Mauriat and His Orchestra

Boasting the second-longest reign at the top for an instrumental (the champ is "Theme From a Summer Place"), "Love Is Blue" has been featured in everything from TV series "Mad Men" and "Millennium" to covers by Frank Sinatra and Andy Williams. It topped the Hot 100 for five weeks.
