Opening for Rush on the Presto tour was "Mr. Big". Part of their act featured guitarist Paul Gilbert playing his guitar with a Makita power drill. During the show at Atlanta's Omni on May 1st, 1990, he accidentally got the drill hopelessly tangled in his hair in front of 15,000 perplexed Rush fans. The next day, Alex Lifeson made this sign, and left it next to the drill onstage, along with an assortment of other tools, including a glue gun, that the road crew thought Paul might prefer. - www.paulgilbert.com, May 1, 1990
