U2 formed in Dublin in 1976, and consists of Bono (given name: Paul Hewson) on vocals, The Edge (given name: David Evans) on guitar, Adam Clayton on bass, and Larry Mullen, Jr. on drums. Signed to Island Records, the band released their debut LP, Boy in 1980, and "I WIll Follow" was the first single.
While "I Will Follow" quickly became a staple at parties and on college radio, the song did not do terribly well in the charts. It originally did not chart (in 1980), although a 1984 live version (from the Under a Blood Red Sky LP) reached #84. On the other hand, Boy definitely attracted some attention and reached #63 on the album charts.
Similarly, the video for "I Will Follow" is relatively rare. By the time MTV launched in 1981, U2's October album was out, and the fledgling music video channel focused on "Gloria," leaving "I Will Follow" as a forgotten classic.
Cool trivia fact: The lyrical inspiration for "I Will Follow" came from the death of Bono's mother (she died when he was 14).
Cool trivia fact #2: "I WIll Follow" is the only song that U2 has played on every tour.
