The Othe Penguins

Here's some information on The Penguins (the music group, not the super adorable animals).

From Wikipedia:

The Penguins were an American doo-wop group popular in the 1950s and early 1960s. They are best remembered for their only Top 40 hit, "Earth Angel" also call "Will You Be Mine". This was one of the first rhythm and blues hits to cross over to the pop charts, peaking at #8 on the national charts.

The original members were:
Curtis Williams (baritone / bass)
Cleveland Duncan (tenor)
Dexter Tisby (tenor)
Bruce Tate (baritone)

The Penguins were one of several doo-wop groups of the period named after birds. Others included The Orioles, The Flamingos, and The Crows. Supposedly the name originated with the smoking habit of the members. At the time, Kool cigarettes used a mascot called "Willie the Penguin" as its cartoon advertising character. Therefore, because they considered themselves "cool", they decided to call themselves "The Penguins".

In a common practice of the time, radio stations frequently featured segregated playlists. Thus, "Earth Angel" was simultaneously recorded by the white group, The Crew-Cuts, in 1955. The Crew-Cuts cover peaked at #3 on the national charts, five spots higher than the Penguins version. The single's success launched the Crew-Cuts' own successful career of recording "crossover"-friendly covers of R&B hits.

The Penguins never had another national hit, but their 1957 cover of "Pledge of Love" reached #15 on the R&B chart.
