Dizzee Rascal is an award winning rapper from the UK and someone whose music i grew up listening to, many regard him as a pioneer of the Grime genre of music which originally emanated from London.
Jonathan Haggerty is a professional Muay Thai practitioner whom i have written about before in this post and is ranked #1 in the super featherweight UK rankings and at #10 in the world rankings.
Dizzee Rascal has been training in Thai boxing for some time now as far as i know and trains in the same gym as Jonathan Haggerty hence why they sparred, the spar itself was more of a move around than a hard spar which is a good way to learn the craft.
