Hi Andrew,
Great question and luckily for you Bob one of my top Ninjas has provided a really sound answer. To answer the question - all flower beds no matter how overgrown are recoverable!
How to remove Turf:
There's no easy way with overgrown flower beds but to lift the overgrown grass culprits out. The mattock is a good idea or if you don't have one a sharp spade. Slice it under the grass around 1-2inchs as if you were lifting turf and remove it.

You can then stack these somewhere upside down, grass side down, where over 6 months they will break down into lovely garden loam (ie top quality soil). See below the kind of depth which can then be laid on top of each other upside down to be fully recycled!

Also, make sure you salvage any plants that may be growing in with the grass. You can probably save them and then at least you have some plants to be starting off the flower bed with!
Cultivating soil:
Then the best way like Bob says it to wait until the ground is relatively moist, never dry or baked. I'd then lightly work it over with a garden fork, rotavator or a scarifyier. Though be careful because a rotavator or scarifier can end up slicing up perennial weed roots too and causing them to be distributed further in the soil. Try and get rid of as many grassroots and weeds as possible before this.

Adding organic matter once this is done such as compost or even a mix of fresh grass clippings can help aerate and improve the soil.

Yes, it's going to be hard work but ultimately worth it. I can guarantee that once you start, the endorphins will flow and you'll become inspired with what you can achieve.
How to plant a flower bed easily:
Once the bed is clear its worth whole watching and reading this guide to create an awesome flower bed.
