It's so nice to hear you say you're going to beat me in every way...

...Doctors fill my room, I'm only dreaming

The story:

The "beat" lyric mistake was realized years before the "doctors".

I assumed that the song's subject might be in a hospital and under medical observation, justifying the misheard lyric.

As is usually the case, I realized the correct lyrics when listening to higher-quality recordings vs. AM radio.
