(The Six O'Clock Triple Shot is a daily feature of three songs that share a common theme, heard weeknights on 94.9 WMMQ)

Tonight, we celebrate Terry "Geezer" Butler's 65th birthday. The mastermind behind most of Black Sabbath's best work, Butler has been a mainstay with the band through its many transformations. Sabbath just wrapped up a huge tour in support of their 2013 LP 13 on July 4th. And, according to the other Sabbath mainstay, guitarist Tony Iommi, the band isn't quite ready to hang it up just yet. He posted this video to his Facebook page.
