Col. O'Neill in “Unfinished Business”

I was not singing. I'd know if I was singing. I don't even know the words to 'Row, row, row…'

[Dr. Fraiser turns on a recording of a surveillance video, in which O'Neill is, indeed, singing]

[on video, singing]...life is but a dream. And row, row, row your boat gently down the stream...

[watching the video] Okay. If you call that "singing".
