Analysis of information sources in references of the Wikipedia article "Hall & Oates" in English language version.
It was a totally conscious decision. Daryl made a joke about it when first got together. He said "I hate being called by my last name, it reminds me of gym class: 'Hey Hall.'" So we said, we are two individuals working together, because we actually started that way — when we first started playing together we hadn't written any songs together. I had written a bunch of songs and he had written a bunch of songs and he said "Look, you play your songs and I'll play behind you," and Daryl would play his songs and I'll play guitar. And that was our working relationship — two guys, two songwriters working with each other. And we didn't even sing together and we actually still don't sing together very often, it's just never been something we ever wanted to do. We didn't want to be the Everly Brothers, or Loggins & Messina, or whatever.
