The Lovin' Spoonful was an American pop-rock band of the 1960s. They were named to the Rock and Roll Hall of Fame in 2000. Their biggest hits included "Do You Believe In Magic", "You Didn't Have to Be So Nice", "Daydream", "Did You Ever Have to Make Up Your Mind." and "Younger Girl"
The band's name was inspired by some lines in a song by Mississippi John Hurt called "Coffee Blues." The Hurt song was generally considered to be either a drug reference to the spoon used to heat and melt heroin, or a reference to the amount of sperm ejaculated by the average male (about a spoonful). The band's leader, John Sebastian says it was the former, but the rumor of the latter persists.
Which brings us to 10cc. They were an English art rock band that achieved their greatest commercial success in the early 1970s. Jonathan King, a flamboyant entrepreneur, producer, and recording artist, signed the band to his UK Records label in July 1972 and dubbed them 10cc.
Pearl Jam is an American rock band that formed in Seattle, Washington, in 1990. Since its inception, the band's line-up has included Eddie Vedder (lead vocals, guitar), Jeff Ament (bass guitar), Stone Gossard (rhythm guitar), and Mike McCready (lead guitar).
The band had called themselves "Mookie Blaylock" - a reference to the then-active All-Star basketball player - when they played their first official show in late 1990 and signed to Epic Records. Concerns about trademark issues meant a name change. They went with Pearl Jam.
In an early interview, Vedder said that the name "Pearl Jam" was a reference to his great-grandmother Pearl, who was married to a Native American and had a special recipe for peyote-laced jam. But in a 2006 Rolling Stone story, Vedder admitted that although he did have a great-grandma named Pearl, the story was a fiction. The band came up with "pearl" and then after attending a concert by Neil Young, they added jam because of Young's extended jam versions of his songs. In the PJ20 movie, it is said that band members came up with "Pearl" to signify something beautiful coming from something ugly.
Despite both of those origin tales (and a rumor that Mookie's nickname was Pearl Jam), the most popular band origin story is that "pearl jam" is another name for sperm. (see the Urban Dictionary)
The success of their album Ten (as in 10cc?), led Pearl Jam to become a key part of the Seattle grunge scene along with Alice in Chains, Nirvana, and Soundgarden.
