Rage Against The Machine legend Tom Morello shared a recent Instagram photo of his long-time friend and cancer-diagnosed Dave Mustaine of Megadeth and sent his ‘get well soon’ message to him.

Here is his letter:

“Wishing a speedy recovery to @davemustaine. Love Peace Sells and he’s the only one in Decline Of Western Civilization Part II that comes across as an intelligent human.

I learned the word “misogynist” from him and his criticism of other bands from that era.”

Also a fan named ikationo asked that:

“Tom, what’s your favorite megadeth song?”

Morello answered:

“@ikatiano Peace Sells is a GREAT jam”
