You folks keep citing the 'music police' and no one has stepped in to point out the error of your ways so I guess it devolves upon me...

A couple of things I'm not fond of, simply because it tends to be a mishmash of sound and kind of disrespects the intent and message of a song is #1, playing two different tunes together (Sorry, Kenny B!) and #2, playing Part A and Part B together, just because the chord changes are the same.

Oh, and I guess there is a third one: Playing a tune that is the antithesis of the song's lyrics. That would include Sailor's Hormpipe, I suppose, if the sung song were a sad lament.

Just because it is possible to do something is not necessarily a good reason to do it.

There now. I'm so proud.
