Styx by BoyerA

Question 1

Dennis DeYoung and the Panozzo twins were in an earlier band with the same name as an obscure New Jersey group from the late ‘50s and (with slightly different punctuation) the duo that had a minor hit with “New York’s A Lonely Town”. Before the expanded group chose the name Styx, they had a different version of this name, abbreviated to three characters. What was the original name (not the later abbreviated name)?
