On 4 March, Richards' partner Anita Pallenberg pleaded guilty to drug possession and incurred a fine in connection with the original airport incident. The drug case against Richards dragged on for over a year. Ultimately, he received a suspended sentence and was ordered to play two free concerts for the CNIB in Oshawa; both shows featured the Rolling Stones and the New Barbarians, a group that Wood had put together to promote his latest solo album, which Richards also joined. This episode strengthened Richards' resolve to stop using heroin. It also ended his relationship with Pallenberg, which had become strained since the death of their third child, Tara. Pallenberg was unable to curb her heroin addiction as Richards struggled to get clean. While Richards was settling his legal and personal problems, Jagger continued his jet-set lifestyle. He was a regular at New York's Studio 54 disco club, often in the company of model Jerry Hall. His marriage to Bianca Jagger ended in 1977, although they had long been estranged.
