Joe Strummer's first band reunited for a tribute concert to remember the punk legend on Sunday.
Strummer died of a heart attack in December
The 101ers had not played together since spliting more than 25 years ago when Strummer left to join The Clash.
The concert, in Notting Hill, west London, also launched the Strummerville charity, which will help disadvantaged youngsters make music.
Strummer, who was 50, died of a heart attack in December.
About £1,500 was raised at the show, with almost 500 people packing into the Tabernacle arts centre.
Former Clash guitarist Mick Jones joined the 101ers on stage for several Clash classics including London Calling.
Strummer formed the 101ers in 1974, reportedly named after the squat where they lived at 101 Walterton Road, Maida Vale, London.
It wasn't sombre - how could it be with rock 'n' roll?
They became well-known on the local punk scene but Strummer left to form The Clash two years later.
Before Sunday, the 101ers had not played together since splitting in 1976.
"You could safely say it was absolutely fantastic. It was full up," 101ers drummer Richard Dudanski told BBC News Online.
"It was very emotive. People went wild musically, and it was a really lovely feeling."
"It wasn't sombre - how could it be with rock 'n' roll?"
Actor Keith Allen also took the stage to read a song Strummer wrote with U2 star Bono about Nelson Mandela.
Also performing were Wilko Johnson, one of Strummer's early inspirations, and Tymon Dogg, who was in Strummer's last band, the Mescaleros.
The Mescaleros' final album, much of which had been recorded before Strummer's death, is expected to be released in May.
The 101ers are also planning to release an album of their material.
