[Playing <i>Johnny B. Goode</i>]

<i>"Way down in Louisiana</i> <i>Down in New Orleans</i>

<i>"Way back up in the woods</i> <i>among the evergreens</i>

<i>"There stood a log cabin</i> <i>made of earth and wood</i>

<i>"Where lived a country boy</i> <i>name of Johnny B. Goode</i>

<i>"He never ever learned</i> <i>to read or write so well</i>

<i>"He could play the guitar</i> <i>just like he's ringin' a bell</i>

<i>"Go go</i> <i>Go Johnny go, go</i>

<i>"Go Johnny, go, go, go</i>

<i>"Go Johnny go, go"</i>

You ever think of running for class president?
