This week 38 years ago, Carl Sagan won the Pulitzer Prize for his book, "The Dragons of Eden"; Bob Marley led the One Love Peace Concert in Jamaica; the Blues Brothers made their first appearance on "Saturday Night Live"; "Coming Home" 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. "Our Love," Natalie Cole
"Our Love" was the big hit off Cole's 1977 album "Thankful," the second of two Cole albums released that year that went platinum.
9. "We'll Never Have to Say Goodbye Again," England Dan and John Ford Coley
The softest rock to ever soft rock.
8. "Jack and Jill," Raydio
This was the first big single for Ray Parker Jr. Yes, the "Ghostbusters" theme guy.
7. "With a Little Luck," Wings
I take it back: This is the softest rock.
6. "Dust in the Wind," Kansas
Kansas' only top-10 hit was one of the many songs allegedly deemed "lyrically questionable" by radio after the Sept. 11, 2001 terrorist attacks.
5. "The Closer I Get To You," Roberta Flack and Donny Hathaway
Beyoncé is a big fan of "The Closer I Get To You." She recorded it for her "Dangerously in Love" album and for duet partner Luther Vandross' album "Dance With My Father."
4. "Lay Down Sally," Eric Clapton
I like 1978 country-blues Eric Clapton.
3. "Can't Smile Without You," Barry Manilow
The Carpenters actually released this song a year before Manilow, though his version is by far the most popular. Another Manilow song popular in 1978: "Copacabana."
2. "If I Can't Have You," Yvonne Elliman
The Bee Gees wrote "If I Can't Have You" and released their own version a month after Elliman's. It took off after Elliman's take turned up on the soundtrack to "Saturday Night Fever." Speaking of...
1. "Night Fever," the Bee Gees
No. 1 for eight weeks, "Night Fever's" reign at the top was sandwiched between other singles they wrote: "(Love is) Thicker than Water" by Andy Gibb and "If I Can't Have You." "Night Fever" ended up as the second biggest single of 1978, according to Billboard's year-end chart. What was No. 1? "Shadow Dancing" by Andy Gibb which, yes, was also written by the Bee Gees.
