The above clip is a perfect example of what would happen if we lived in a world without song leaks. After attending the video shoot for AC/DC’s Black Ice first single “Rock N’ Roll Train,” one fan was eager to show other AC/DC fans what the new song sounded like. But instead of just recording the song’s video playback on his cell phone like a normal person, this fan opted to get creative, dressing up like lead singer Brian Johnson and attempting his own YouTube version of the song. The result is a four-minute screech fest which in no way can possibly help Black Ice album sales. Right around when the guy starts air-guitaring Angus Young’s solo, we switch to our next video, made by another AC/DC fan. This video below is the by-product of what happens when a guitarist’s friend who attended the video’s filming “hummed” the riff to the guitarist, who was not at the video shoot. The guitarist’s interpretation sounds like a pretty kick-ass combination of Bachman Turner Overdrive’s “Hold Back the Water” and KISS‘ “Firehouse,” but it’s slightly more tolerable than the Brian Johnson impersonator. As reported yesterday, we’ll all be able to hear the proper version of “Rock N’ Roll Train” when the single hits radio August 28th.
