Or this one...

Kendall wakes up one morning the fetch the Newspaper, The Mudcat Curmudgeon when he finds a guitar left on his doorstep. He takes it to local guitar guru/deity Rick Fielding, who is totally stumped as to it's make. He sends Kendall on his way with more questions left unanswered than when he arrived. Rick expediently goes back to calculating an angle at which the hand can be placed so as to utilise the "thumb wrap-around" on 1919 Hawaiin slack-key guitar.

When Kendall takes it to the Mudcat Cafe and tries playing it, he is suddenly blessed with universal love for music. As stunned visitors and denizes watch, he begins playing everything from The Beatles to Django to Slash to Hendrix to John Williams. He begins spouting song lyrics uncontrollably, making Matt_R squeal with all other extremely nervous. There is the classic climax when Matt & Kendall sing Queen's "Friends Forever".

At the end, Sinsull gets pissed and breaks the guitar over the pinball machine after Kendall starts serenading her with Yardbirds tunes ala-Jeff Beck. He becomes his usual grumpy self again, tells Matt R to shut up, and goes back to Utah Phillips.

The videorecording of Kendall singing "Get Myself Arrensted" becomes a subject of blackmail in a later episode....
