 To encourage fans to buy more than one copy each of the single, he released three different versions.The flip-side of "Bunsen Burner – The Hit Mix" was a cover of "The House of the Rising Sun" recorded at Abbey Road Studios and featuring 900 of his fans on backing vocals, each of whom was credited by name on the single's sleeve.Thanks to this second hit he has now been able to release his "Greatest Hits" album.
