{Words & Music: Hazel O'Connor}  Ah come on  Let's go  Let's all play mums and dads, come on  Where do babies come from, mum?  Shut up you naughty boy  And put your clothes back on  [CHORUS:]  Mucky pup, cover up  Strip it down, cover round  Dirty muck, cover up  Look at us we got cover plus  'Cos we're all grown up, we're all grown up  Peel off black nylon in the red light  Silly old men leer through their gun sights  Naughty girl turn round  I'll show you what's right  [CHORUS]  Dirty muck, cover up  Strip it down cover round  Dirty muck, cover up  Strip it down cover round  Dirty muck, cover up  Strip it down cover round  Mucky pup cover up  Look at us got cover plus, look at us got cover plus  We're all grown up, we're all grown up  Why don't you go and fix your face, up good  Why not buy some paint and hide your wood worm good  But let the children play the way they feel and should  Dirty muck, cover up  Strip it down, cover round  Mucky pup, cover up  Look at us got cover plus  Dirty muck, cover up  Look at us we got cover plus  'Cos we're all grown up, all grown up  All grown up [Repeat to Fade]
