In last week's Season of the Ukulele, people had to play songs from one of the "Guardians of the Galaxy" soundtracks. I didn't have much time because we were getting ready to go on vacation, so I did a quick version of "Mr. Blue Sky", which I've played in the past. This gave me a chance to use my Electro Harmonix Mel9 pedal, which simulates the sound of the Mellotron keyboards of the late '60s and '70s, toward the end.
