Bert Weedon, also known as ‘Mr. Guitar,’ recently passed away on April 20 at his home in Beaconsfield, England at the age of 91. Weedon, who penned the ‘Play in a Day’ Guitar Guide back in 1957, inspired the guitar playing of many notable greats from Pete Townshend to Eric Clapton, and even members of The Beatles.

Black Sabbath bassist Geezer Butler recently took to his own website to post about the loss of Weedon and the impact he had on him, bandmate Tony Iommi, and all guitar players of his generation. He talks about why his book was so effective and even notes that Black Sabbath wouldn’t exist without it. That's some pretty heavy praise!

Read Geezer's full journal post below:

I had stopped commenting on deaths and disasters, because my “journal” was starting to resemble an obituary column. However, I cannot ignore the passing of Bert Weedon. Some of you won’t have heard of him, but I can safely say that many UK and Ireland guitarists from John Lennon onwards throughout the 1960′s and 70′s, would probably have never learned to play without Bert Weedon’s Play In A Day book. He produced a book with pictures of chords, rather than musical notation, making it possible for those of us who couldn’t afford music lessons, or didn’t read music, to gradually learn basic chords on the guitar. I know Black Sabbath wouldn’t exist without his book, since both Tony Iommi and myself learned to play guitar chords from it. RIP Bert!

Seems like we all we Mr. Weedon our gratitude for influencing some of the most iconic rock bands of all time. Thank you Mr. Guitar!
