1. Terry Jacks - "Seasons in the Sun"

With a sort of jaunty melancholy, Jacks' summery sing-along was a true international effort. This cover of Belgian Jacques Brel's "Le Moribond" was translated from French into English by American poet Rod McKuen. The Canadian Jacks hit No. 1 with the massive-selling tune in the U.S., U.K. and Canada. However, his follow-ups failed to crack the Top 40 in our country.

2. MFSB - "TSOP (The Sound of Philadelphia)"

Acronym lovers, let's boogie! "Mother, Father, Sister, Brother" wrote this groove as the theme song to Soul Train. It became one of the earliest disco songs to top the Billboard pop charts.

3. David Essex - "Rock On"

Oozing cool restraint, "Rock On" somehow managed to be so minimal it bordered on ambient while sounding as heavy as anything. A Brit reading this might be baffled to find Essex on this list, but the guy never scored another hit in the States. "Rock On" reached No. 5, while "Lamplight" pooped out at No. 71.

4. Blue Magic - "Sideshow"

MFSB was not the only "sound of Philadelphia." This soft soul group cracked the Top 10 with "Sideshow." The similarly circus-themed "Three Ring Circus" did barely breach the Top 40 later that year, which could technically exclude them from this list, but we just love the song. So there.

5. Paper Lace - "The Night Chicago Died"

Straight outta Nottingham like Robin Hood, Paper Lace might have had two massive hits in the U.S. Their tale of a shootout between Chicago police and gangsters spent a week at the top of the charts. The group also wrote "Billy Don't Be a Hero," a No. 1 hit in the U.K. that same year, though it was Bo Donaldson and The Heywoods who took the song to No. 1 here with their cover version.

6. Johnny Bristol - "Hang on in There Baby"

A regular on the soul charts throughout the decade, Bristol's sole solo cut to break big on the pop charts was this relaxed proto-disco song. Bette Midler would later cover it.

7. Mocedades - "Eres Tú"

Spain's entry into the 1973 Eurovision song contest, "Eres Tú" became one of the rare songs en español to crack the Top 10 in America.

8. Dave Loggins - "Please Come to Boston"

Dave "second-cousin of Kenny" Loggins wrote hits for others before grabbing the mic for this easy-listening tale about a heartbroken vagabond.

9. Sister Janet Mead - "The Lord's Prayer"

Australian Catholic nun Janet Mead, pioneer of the "rock mass," had listeners headbanging their way into Heaven. Her shredding "Our Father" soared to No. 4 on Billboard. Surprisingly, she was not the first nun to score a hit. Sœur Sourire the Singing Nun went to No. 1 in 1963 with "Dominique."

10. The First Class - "Beach Baby"

A studio project of British songwriter John Carter, the First Class staked its claim to the song of the summer with foot-stompin' "Beach Baby," which climbed its way to No. 4.

11. Reunion - "Life Is a Rock (But the Radio Rolled Me)"

With its early nostalgia for the good ol' days of rock & roll, this novelty number was essentially the Happy Days of one-hit wonders. Joey Levine, no stranger to bubblegum, had previously sung "Yummy, Yummy, Yummy" for the Ohio Express. He does an impressive job of breathlessly rambling off references to the 1950s and '60s.

12. Carl Douglas - "Kung Fu Fighting"

Perhaps the ultimate one-hit wonder of the 1970s, "Kung Fu Fighting" helped popularize the martial arts craze, which saw the rise of suburban dojos and television airings of Hong Kong movies.

13. Prelude - "After the Gold Rush"

Think of them as the Pentatonix of the 1970s. The British trio's harmonic take on Neil Young's classic spent five weeks on the Billboard Hot 100 in early 1974, peaking at No. 22.

14. Byron MacGregor - "Americans"

Believe it or not, there were two recordings of Canadians speaking their praises of the U.S. of A. on the Billboard Hot 100 the week of February 9, 1974. Toronto journalist Gordon Sinclair penned this tribute to "the most generous and possibly the least appreciated people in all the world" (that's us). His recording reached No. 24. However, news anchor Byron MacGregor took the same piece all the way to No. 4, perhaps thanks to the added backing of the Detroit Symphony Orchestra playing "America the Beautiful." Put it on your Fourth of July playlist.
