Finally, an Unknown Song has been fully identified for the first time since early October. US #15 is "Wheels in Motion" by David Chesky. Special thanks to "Noah S" on youtube for showing me Dave Volsky's post of this song. The only album I can find with this song is Victory Fever: Fanfares for Sports and Sporting Event, which seems to be a recent compilation of Chesky's sports stuff along with some songs by other artists. All of Chesky's tracks from this album are included in the youtube channel/account that's linked above (they are not all together, annoyingly). I have no idea what production music label originally housed them. My guess is that it's either the NFL Music Library LPs or perhaps Manhattan Music since Chesky is credited on a couple of their albums on Discogs.
