By any chance was the song a vocal version of "Tequila"? "Tequila" by The Champs in 1958 is an instrumental featuring a funky sax burping out a rhythm that could conceivably be vocalized as your "eo oh oh oh eo oh". The only spoken word in the whole song is "Tequila!" It was featured in a Pee Wee Herman movie, Pee Wee's Big Adventure, I think. That was about what 10 or 15 years ago?
