Congo Don Patito - Brilla Tu Diamante Loco
A modern Fausto Papetti in reggae, improbable and disarming in his remakes.
(only the covers don’t count those of Fausto)
And 'Brilla tu diamante loco' makes it clear what the "cover" is.
 
Hammer - Manic Depression
In this piece, THERE IS NO guitar.
 
Milli Vanilli - Girl You Know It's True
In theory, it was "visual performance." That is, they were image boys, moving their mouths while others provided the voices.
However, this was not specified in the credits of the LP.
It wasn't specified because it was taken for granted; it was said: if they're on the cover, who do you think is singing?
A story that ended badly.
