The Importance of Tuning Your Guitar

"I was playing guitar in the control room With the producer there And it was kind of a really exciting part of the song Almost like a who part" "He had me tune the chord up on the 12th fret Rick, are you listening? He had me tune that fretted chord So then later I don't know why I'm screaming Later when the record was being mixed by Dave Sardi, whose name can be mentioned here he said, your guitar's Everything's tuned to and if you want, I can put a guitar on it That's slightly out of tune."
