Old southern rock song (fly fly fly let it fly)

There's an old southern rock song I hear on the radio every now and then It sounded a lot like The Steve Miller Band. the only part of the song I remember was "fly fly fly let it fly" or it could have been "by by by pass it by". It's a pretty common song, but that's all I got. Thanks in advance

"Let It Ride" by Bachman-Turner Overdrive
