the tune is a public domain piece, it is caliope music of generic origin
there are plenty of examples of this type of thing in music through the ages
it's like "travelling music" or what would play whilst the organ grinders monkey danced

As to the actual recording, there is a good chance it was redone specifically for OWN, there are also sample libraries which are available to artists which are paid for once and contain a large variety of sounds, effects etc which may be used lisence and credit free by subscribers/owners.

Aerosmiths drummer released one of these collections of all drum tracks, samples etc a few years back.
