Let's talk about ...
I'm sure you all remember the hit 'Let's talk about sex' (and you're probably humming the tune already!) from Salt'n'Pepa.
Well, did you know they did a remake of this song, called 'Let's talk about AIDS'? The lyrics were changed to address the worldwide spread of HIV/AIDS and how to prevent it. So get your rap on and take a listen: the song was made in 1990 and it's still as modern and actual as it was then!
