Eli's Pork Chop - Little Sonny

Despite picking up 60+ CDs over the weekend (yes...I know...) I couldn't resist a compilation called Shattered Dreams - Funky Blues 1967 - 1978 for 50p from one of my local charity shops. It's a blinder (you can buy a copy for £10+ on eBay and it's still well worth it at that price) and this is one of the best tracks on there. Has the harmonica ever sounded so funky?
