ABC once broadcast a 4-part television special in 1960 called The Frank Sinatra Timex Show: Welcome Home Elvis. This was to be the hip-swiveler’s first television appearance in three years since being discharged from military service.

At one point, Elvis threatens to get upstaged by a fresh, jazzy near-instrumental but for the phrase, “uh oh” that sounds as if voiced by a pair of “nutty squirrels” (i.e., poor man’s Alvin & the Chipmunks):
“Uh Oh” The Nutty Squirrels 1959
“Uh Oh” – the debut single by The Nutty Squirrels, a creation of Sascha Burland and Don Elliott – would enjoy release in the US, UK, Canada, Germany, Australia & New Zealand. The duo would follow “Uh Oh” with “Uh Huh” (a 4-song EP) and a third single, “Eager Beaver” b/w “Zowee” — all tracks from their debut Hanover album — before making the leap in 1960 to almighty Columbia, who issued an LP and Christmas 45.
Wikipedia claims that  “The Squirrels actually preceded the Chipmunks on television in an animated cartoon, but with much less success”;  “Uh Oh (pt. 1)” just about grazed the Top-40 (#45), while “Uh Oh (pt. 2)” climbed to #14 Pop and #9 R&B in 1959; and  The Squirrels would have one last fling with commercial success in 1976 as “Shirley & Squirrely” via a CB-radio novelty single, “Hey Shirley (This is Squirrely),” that reached #48 Pop and #28 Country.
