Which channel gets the vocals on Nowhere Man?

This question is directed mostly to Beatles fans out there, but anyone can join in. The other day I was listening to the radio in my car when the DJ played Nowhere Man. Well the vocals began "He's a real Nowhere Man sitting in his Nowhere land" came out of the left channel while the music was in the right channel. When I got home, I put on Rubber Soul and when I played Nowhere Man, it was the opposite, the vocals came out of the right channel and the music came out of the left channel. In your experience, should the vocals be in the right channel or the left channel?
