This week 42 years ago, 600,000 people attend the Summer Jam at Watkins Glen in New York (Grateful Dead, The Allman Brothers Band and The Band perform); Skylab 3 launches into space; "Enter the Dragon," Bruce Lee's final film, tops the box office; and the following songs are the most popular in the U.S., according to Billboard's Hot 100 chart archive.

10. "Give Me Love (Give Me Peace On Earth)," George Harrison

"Gave Me Love" was Harrison's second No. 1 song as a solo artist (the first: "My Sweet Lord"), and it bumped Paul McCartney and Wings' "My Love" from the top spot.

9. "The Morning After," Maureen McGovern

This rather sunny theme to the rather unsunny ship disaster film "The Poseidon Adventure" was oddly released as a single five months after the film premiered. It won the 1972 Oscar for best original song (among the competition: "Ben" by Michael Jackson, which is from a film about killer rats).

8. "Boogie Woogie Bugle Boy," Bette Midler

Midler's cover of the 1941 hit for the Andrews Sisters appears on her debut album "The Divine Miss M," which also included covers of "Delta Dawn," "Leader of the Pack" and "Do You Want to Dance?"

7. "Kodachrome," Paul Simon

Yes, in case you're wondering, Kodak used this song in commercials in the '90s. By the way, the only country where this song went to No. 1: Canada. It topped out at No. 2 in America.

6. "Diamond Girl," Seals & Crofts

Did you know Crofts' first name is Dash? I have a whole new appreciation for him/them.

5. "Will It Go Round in Circles," Billy Preston

"Will It Go Round in Circles" was one of two solo No. 1 hits for Preston; he also was credited on the Beatles' "Get Back."

4. "Smoke on the Water," Deep Purple

The distinctive guitar riff? Total Guitar magazine's readers ranked it No. 4 in its list of Top 20 Guitar Riffs Ever. (No. 1: "Sweet Child O' Mine" by Guns N' Roses)

3. "Shambala," Three Dog Night

"Shambala" wasn't just a hit for Three Dog Night. B.W. Stevenson released his own version a week earlier. Daniel Moore, the songwriter, co-penned Stevenson's other big hit, "My Maria."

2. "Yesterday Once More," the Carpenters

In her forward for the Karen Carpenter biography "Little Girl Blue," Dionne Warwick wrote that she performed this song in Las Vegas the night before Karen's death in 1983.

1. "Bad, Bad Leroy Brown," Jim Croce

Topping the charts for two weeks, "Bad, Bad Leroy Brown" was Croce's last No. 1 hit while alive. He died in a plane crash on Sept. 20, 1973. Croce's "Time in a Bottle" reached No. 1 in December of that year.
