The Beagles

From Muppet Wiki

The Beagles are a rock band (or rather, "bark and roll" group) on Dog City. A parody of the Beatles, the Beagles are seen, alluded to, or heard in several of the animated stories, supplying a cultural background for Dog City. Ace Hart is generally resistant to the new "bark and roll" sound, and in particular the Beagles' ubiquiotous hit "I'm Your Doggy." The song gets frequent play on WFIDO, and the group performs concerts at the Dog City Water Bowl.
