Here's a tune I never knew the name of until the arrival of the magic tune finding machine http://tunepal.org/tunepal/index.php.

I see that people now even have telephones with this facility on them.  If someone sneezes at a session these days there's likely to be an iphonophile who will be try to identify the sneeze as some polka or other.  Any extraneous noises in this recording have passed without being interpreted as anything other than normal noise - any other noises are supposed to be the tune.
