The Pirates of the Caribbean swashbuckler franchise is synonymous with Johnny Depp, who played the drunk and eccentric pirate Jack Sparrow. However, Depp, who is also a musician, had brought several high-profile friends to the franchise.

Ronnie Platt, the frontman for legendary rock band Kansas, shared an important update this week in his battle against cancer. Platt returned to social media on Thursday to let fans know how the meeting with his oncologist went.

Kansas, the classic rock band that became popular in the 1970s, has canceled a number of shows while the band’s lead singer battles cancer. Vocalist Ronnie Platt, 62, revealed last week that he needs time off for thyroid cancer treatments and added that it has a 99% survival rate.
