The 101ers were a pub rock band from the 1970s, notable as being the band that Joe Strummer left to join The Clash. Formed in London in May 1974, the 101ers made their performing debut on 7 September at the Telegraph pub in Brixton, under the name El Huaso and the 101 All Stars. The name would later be shortened to the 101 All Stars and finally just the 101ers. The group played at free festivals such as Stonehenge, and established itself on the London pub rock circuit prior to the advent of punk. The group was named for the squat where they lived together: 101 Walterton Road, Maida Vale, although it was for a time rumoured that they were named for "Room 101", the infamous torture room in George Orwell's novel Nineteen Eighty-Four.
The 101ers were supported by the Sex Pistols at the Nashville Room on 3 April 1976, and this is when Strummer claimed he saw the light and got involved in the punk scene.
