Bramlett continued to contribute vocals to recordings by other artists, including Little Feat and the Allman Brothers Band. In 1979, Bramlett travelled to Havana, Cuba, to participate in the historic Havana Jam festival, alongside Stephen Stills, the CBS Jazz All-Stars, the Trio of Doom, Fania All-Stars, Billy Swan, Weather Report, Mike Finnegan, Kris Kristofferson, Rita Coolidge and Billy Joel, plus an array of Cuban artists such as Irakere, Pacho Alonso, Tata Güines and Orquesta Aragón. Her performance appears in "Havana Jam '79" a documentary film by Ernesto Juan Castellanos. While on tour with Stills in 1979, Bramlett punched Elvis Costello in the face at a hotel bar in Columbus, Ohio, after Costello referred to James Brown as a "jive-ass nigger" and Ray Charles a "blind, ignorant nigger." Costello apologized at a press conference in New York City a few days later, claiming he had been drunk and had been trying to be obnoxious in order to bring the conversation to a swift conclusion. According to Costello, "it became necessary for me to outrage these people with about the most obnoxious and offensive remarks that I could muster." Bonnie guest-starred in an episode of "Fame" in 1986. After exploring gospel music in the 1980s, Bonnie married Danny Sheridan in 1988 and she changed her professional name to Bonnie Sheridan. He became her manager and produced her next recordings. She fronted their group the Bandaloo Doctors, with their self-proclaimed "revolutionary hard rockin' blues." The group's music attracted the admiration of many Hollywood celebrities. In 1990, Bonnie met Roseanne Barr at a rehab program fund-raiser, and she was soon cast as a semi-regular on the hit ABC series "Roseanne". Bonnie (credited as Bonnie Sheridan) played a co-worker and friend (named Bonnie) of Roseanne Barr's character Roseanne Conner, with Danny Sheridan occasionally writing music and appearing as the character Hank the bass player. In 1992, the Bandaloo Doctors toured as the opening act for Ringo Starr. Bonnie was cast in the 1991 movie "The Doors", playing a bartender. She also appeared in the Andrew Davis film "The Guardian" (2006), starring Kevin Costner and Ashton Kutcher. In 2002, Bramlett returned to her musical roots, releasing the album "I'm Still the Same".
