All this sound system talk reminds me of a group I love. Saw them back in 70s a lot.

Lyrics
Rock and Roll on the radio
, Hear it every place I go,
Stick McGhee singing Spo-Dee-O
Let it rock to your very soul
Well the Jacquet on the saxophone
, Plays it like you never heard before
, Can't you feel him getting so high
, Let it rock to your very soul,
Well Let It Rock to your very soul,
Rock to your very soul
, Hear it on the radio
, Rock to your very soul,
Well let it rock
Everybody knows they got to move
, When they hear that funky rhythm move
, When there's nothing left for you to do
, Let it rock to your very soul,
Well Let It Rock to your very soul
, Rock to your very soul
, Hear it on the radio,
Rock to your very soul
, Well let it rock o Well let it rock
