Tommy Amper (b. 1962), sometimes credited as Thomas Amper, is a German singer, voice actor, and dubbing director who has been heard in multiple Muppet projects.
He dubbed the singing voices of Bear and Pip on Der Bär im grossen blauen Haus (Bear in the Big Blue House) and related albums. He sang for Kermit the Frog in the Studio DC: Almost Live specials (and dubbed Billy Ray Cyrus in the first special) and in Die Muppets: Briefe an den Weihnachtsmann (A Muppets Christmas: Letters to Santa, where he also dubbed the postal worker). He served as musical director on the above, overseeing any arrangement adjustments and the vocal recordings, and his studio Jamzone was used for the sessions. For Die Muppets, he dubbed several singing roles, including Human Walter and Wayne.
In addition to writing and recording a few solo albums, Amper's other dubbing roles (often for Disney projects) include Billy Ray Cyrus in the Hannah Montana franchise, Taye Diggs in Chicago, Patrick Warburton in Underdog (and as Kronk in The Emperor's New Groove), George Sanderson in Monsters Inc., and the singing voices of Dr. Facilier in The Princess and the Frog, Guy Pearce in Bedtime Stories, and Brom Bones in The Adventures of Ichabod and Mr. Toad.
