There are at least two artists called The 4 of Us:

1) an Irish rock/acoustic/alternative band from Newry, Northern Ireland.

2) an American psychedelic rock band from the sixties

1) The 4 Of Us are a rock band from Newry, County Down, Northern Ireland, best-known outside Ireland for their output in the late 1980s and early 1990s. Of the four founding members from 1988, only brothers Brendan Murphy and Declan Murphy have remained continuously part of the group; the other members have varied.

The band released their first album, Songs for the Tempted, with CBS Records in 1989, with the single "Mary", becoming one of the most played songs on Irish radio that year. Consequently, the album went double platinum in Ireland and won Best Album of the Year at the Irish Music Awards, defeating the internationally-known act U2. After a successful second album, Man Alive (in 1992), the band lost momentum scrapping the release of a proposed third album. They did not separate however, and eventually returned to recording albums, releasing the largely acoustic-based Classified Personal in 1999. In November 2006 the band released their album Fingerprints.

2) The 4 Of Us were a garage / psychedelic rock band from sixties. After graduating from high school in 1966, Glenn Frey played for a while with the local band The 4 of Us, modeled after The Byrds.

Tracks by them such as "Baby Blue", "I Feel A Whole Lot Better" and "You Gonna Be Mine" appear on various compilations of 60s psychedelia.

Afterwards, Frey, Henley, Meisner and Leadon formed the Eagles, with Frey playing guitar and keyboards and Henley playing drums. The band went on to become one of the world's best-selling bands of all time. Frey wrote or co-wrote (often with Henley) many of the group's songs, and sang the lead vocals on a number of Eagles hits including "Take It Easy", "Peaceful Easy Feeling", "Already Gone", "Tequila Sunrise", "Lyin' Eyes", "New Kid in Town", "Heartache Tonight", and "How Long".
