The song is by Rod Stewart... Young Hearts (be free tonight). I'm listening to it right now. He doesn't actually say the lyrics from the commercial, so in that respect it was made for the commerical and added 'the wheels go round and round' but the music is definitely from this song...
This drove me absolutely mad trying to find out what the song is. I hope you and everyone else looking for this song reads this and SHARES MY VICTORY!!!
