Cover art for Heavy Bells lyrics by J Roddy Walston & The Business

Please see my replies to the other two comments...no one else seems to recognize that the "red symbol" flashing throughout the video is the design of a circular "insert" used for a 45 rpm vinyl record's center hole that enables you to play a 45 rpm "single" on a record player meant for 33 1/3 rpm LP's. Yes, I am THAT old lol.

I'm old enough to have used those plastic inserts . . but the red symbol could be many things, not just the 45 insert thingy . . .

they are parallel lines, that change direction (i paused the video at :33 - ha!) they look more like the V in the van halen logo - only sideways . . . :)
