Linkin Park singer Chester Bennington had several promotional appearances in the works, prior to his sudden death on Thursday morning. It has been reported that he was scheduled to take part in a photo shoot with his band only hours after his body was discovered in his Palos Verdes Estates home, in California, and now it has been revealed that he and his band mates also filmed a segment for Apple Music's "Carpool Karaoke" series less than a week before his passing.

Band was to appear with actor Ken Jeong

The series, a spin-off of James Corden's popular "The Late Late Show" segment, has produced 16 stand-alone episodes which mix musical guests with Hollywood celebrities, taking turns singing and driving behind the wheel.

It was first revealed that Linkin Park had collaborated with actor and comedian Ken Jeong on July 14 after the band posted a behind-the-scenes photo of the shoot to their Twitter account.

The segment had been filmed to promote the band's upcoming world tour, which has since been cancelled in light of Bennington's death. That tour would have coincided with the release of Linkin Park's 7th studio album "One More Light."

There has been no word from the producers of "Carpool Karaoke" or Apple Music if the band's episode will air as planned once the show premieres online on August 8.

However, Jeong did send a message of condolence to Bennington's friends and family via Twitter.

Cause of death confirmed by Coroner

Bennington's official cause of death was confirmed by the Los Angeles County coroner on Friday afternoon, along with additional information about how his body was found the day prior.

According to Variety, a staff member for the Los Angeles Department of Medical Examiner-Coroner confirmed that Bennington's body was found hanging in his bedroom and that a bottle of alcohol was found in the room, although not near the body itself. Bennington had a long and relatively open struggle with alcoholism and depression.

An autopsy is still pending and it could be weeks before a toxicology result is issued.

Many links have been made between Bennington's death and the suicide of Soundgarden singer Chris Cornell in late May, especially as Thursday would have been Cornell's 53rd birthday. The pair had been close friends and it has been reported that Bennington had been struggling with the death in recent months. He was hardly able to finish performing the song "One More Light" -- about the loss of a friend -- in the days following Cornell's passing, according to Linkin Park's guitarist Mike Shinoda.

Without drawing any parallel's Cornell's wife Vicky tweeted about Bennington's passing before the news had been officially released to the public.
