On Tuesday morning, one of the most successful music producers ever, 90-year-old Beatles producer George Martin, died. The news was met with an outpouring of affection and grief across the internet for the man who had been lovingly nicknamed the “fifth Beatle.”

But in another segment of the internet, the news of George Martin’s death sounded an awful lot like a death knell for another beloved artist whose name differed by just two letters: George R.R. Martin, the 67-year-old creator of Game of Thrones whose health has been closely monitored by fans since the thus-far incomplete series became a runaway hit.

Fans reacted with an emotional cocktail of grief, shock, guilt, relief, and generally conflicted.

SOMEONE NAMED “GEORGE MARTIN” DIED AND I THOUGHT IT WAS GEORGE R R MARTIN AND I ALMOST SCREAMED IN CLASS

RIP George Martin not to be confused with George R R Martin who isn't allowed to die until he finishes writing the next book.

Is it bad that I was relieved when I realised it was George Martin who had died and not George RR Martin? I need to know the end!

I'm sorry to hear that #GeorgeMartin has died but I'm glad I was mistaken in thinking it was #GeorgeRRMartin

#GeorgeMartin For one second, I thought it was George RR Martin, and thought I'd never be able to read Winds of winter.

The two have also had their photos mixed up, which likely generated more confusion:

The confused fans however were outweighed by the flood of comments mourning the passing of producer George Martin, and the tributes celebrating his life:

George Martin saw something in the Beatles no one else did. Other record execs in England told them "bands with guitars are on the way out."

Just want to say this today… Thank You George Martin.
