Amy Tuck grew up in a small town in Ohio and studied music at CSULB.  She has since performed in Los Angeles, Las Vegas, Houston, Singapore, Kansas City, and finally Denver where she is extremely happy to call home.  After playing for numerous clubs and moving from city to city, she met her husband John, and together they created Colorado Keys.


John Tuck studied music all through college at the Chicago College of Performing Arts and University of Kentucky.  He was a member of the U.S. Navy’s premiere contemporary music ensemble The Electric Brigade until taking a job as the Assistant National Entertainment Director for live music venue chain Howl at the Moon where he met his wife Amy.  They have since formed Colorado Keys together.


Pamela Machala grew up in a musical family and started piano at the age of 5.

Now a freelancer and award-winning singer/songwriter who fronts the Pamela Machala Band, she can be found performing all over Colorado’s Front Range.


Jon Sherman has done it all. He started singing, playing piano and drums at the age of seven. By the time he was ten he was acting in commercials, films and Off-Broadway, but music was the biggest passion for him. Jon started dueling pianos in 1992 at Jake Ivory’s in Boston after attending Berklee college of music. After a short time in Aukland, New Zealand, performing a Dueling Pano Show, he started with Howl at the Moon in San Antonio, TX. Jon moved to Denver in 1999 to work at Sing Sing Dueling Piano Bar. In 2011 Howl At The Moon bought and took over Sing Sing’s location and he continued to work for Howl until 2020, when the Covid pandemic hit. Jon still makes his home in Denver and does freelance piano-sing- along clubs across the country including; The Shout House San Diego, “The Big Bang” Nashville, “Michael Murphy’s” Oklahoma City, “Howl2go”, “Howl At Sea” on Norwegian Cruise Lines, and most recently in “Duelers” Piano Bar in Coeur d’Alene, ID.
