Supposedly Muscles was the name of Michael's pet python at the time.

How do you define cool?
Is it having loads of money? A fierce attitude?
Being good in bed? There are tons of different ideas and ways to define cool. But one of 'em that I think pretty much sums it up is when you are slightly over the hill and everyone knows but doesn't care. Like when Kylie tried to be indie and had short red hair and no-one bought her albums. But she was at the height of her cool. Or when good old Sharon Stone was released from the geriatric ward to make 'Basic Instinct 2' when she was just about to turn 80. The movie sucks harder than Beyonce's new single but she looks good in her wig and silicone tits and she was the toast of London for a couple of months. Then we have the number one example. Diana fuckin' Ross. In 1982 she was well over the hill. Middle-aged with Supremes well and truly behind her as well as her only excellent solo effort 'Diana'.
WHAT DO YOU DO? Well if your cool you just don't care that you are over the hill and call your pal Andy Warhol and tells him (not nicely) to do the album cover and then you call your Princess Michael Jacko and demands a hit single about 'Muscles' and to save in on some money you get Mike to do the backing vocals as well.
Period.

I want 'Muscles':
