In 1966, Baker was beaten, probably while attempting to buy drugs, after performing at The Trident restaurant in Sausalito. In the film "Let's Get Lost", Baker said an acquaintance attempted to rob him but backed off, only to return the next night with a group of men who chased him. He entered a car and became surrounded. Instead of rescuing him, the people inside the car pushed him back out onto the street, where the chase continued. He received cuts and one of his teeth was cracked. This incident has been often misdated or otherwise exaggerated partly due to his own unreliable testimony on the matter. The breaking of his tooth did, however, ruin his embouchure, leaving him unable to play trumpet. He worked at a gas station until concluding that he had to find a way back to music, and retrained his embouchure. After developing a new embouchure resulting from dentures, Baker returned to the straight-ahead jazz that began his career. He moved to New York City and began performing and recording again, including with guitarist Jim Hall. Later in the 1970s, Baker returned to Europe, where he was assisted by his friend Diane Vavra, who took care of his personal needs and helped him during his recording and performance dates. From 1978 until his death in 1988, Baker lived and played almost exclusively in Europe, returning to the U.S. once a year for a few performances. This was Baker's most prolific era as a recording artist. In 1983, British singer Elvis Costello, a longtime fan of Baker, hired the trumpeter to play a solo on his song "Shipbuilding" for the album "Punch the Clock". The song exposed Baker's music to a new audience. Later, Baker often featured Costello's song "Almost Blue" (inspired by Baker's version of Ray Henderson’s “The Thrill Is Gone;" not to be confused with the Roy Hawkins song of the same name, made famous by B.B. King) in his concert sets, and recorded the song for "Let's Get Lost". In 1986, "Chet Baker: Live at Ronnie Scott's London" presents Baker in an intimate stage performance filmed with Elvis Costello and Van Morrison as he performs a set of standards and classics, including "Just Friends", "My Ideal", and "Shifting Down". Augmenting the music, Baker speaks one-on-one with friend and colleague Costello about his childhood, career, and struggle with drugs. Baker recorded the live album "Chet Baker in Tokyo" with his quartet featuring pianist Harold Danko, bassist Hein Van de Geyn and drummer John Engels less than a year before his death, and it was released posthumously.
