Its not a competition its a song.

He wants a caller to provide the requisite claps and snaps. A guy auditions for the role, but Tom thought he was terrible. Another caller puts his girlfriend up for the part, but she got the wrong sides and does the Mercury mouth-noises instead of the proper backing. Tom considers searching for a karaoke version, but he doesn't have the time. He sings along with the record:
Tom Scharpling (ft. David Bowie & Farrokh Bulsara) - "Under Pressure"
Tom declares Bowie the winner. My pick: Tom Scharpling! This was easily the most exhilarating version of the song ever performed -- Tom's operatic "Why-why-why" into the rousing plea for love trumps the power of the original".
