One of the funkiest cuts ever from reedman Harold Alexander – served up here in the 45rpm single version, which is short, tight, and really concentrates on the funky drums at the core – although still also topped with plenty of fierce funky flute from the man himself! Speaking of funky drums, Pretty Purdie is on the flipside with "Heavy Soul Slinger" – a cut that definitely earns its name, as the funky drums mix with great conga, massive bass, and this warm organ line that really sends the whole thing home! 7-inch, Vinyl record

One of the best versions of "Funky Four Corners" we've ever heard! The bass is rattling along at a level so loud and heavy that it's bound to pop the top off your speaker – while Jerry screams and shouts his way through the lyrics in a way that would make James Brown proud, a fact that he even acknowledges when he shouts "Sorry JB!" at one point in the cut! "Soul Lover" is fantastic too – a funky answer song to "Tramp", with a similar hard sock beat, and a hard break at the intro, which is augmented here by conga work! Both cuts are great – and one of the best singles ever by Jerry O! 7-inch, Vinyl record

Two classic hard funky slammers from Andre Williams! "Do the Popcorn" is an unbelievable non-stop cut, with jangling guitars in chorus all the way through – and Andre speaking in a raspy sexy voice, while a funky female chorus chimes in from time to time. Oh, and did we mention the drums? At some points, they break out in a rat-tat-tat blast that sounds like a machine gun in an elevator shaft! "Gonna Be Fine" is pretty nice, too – and has a tight Chicago groove! 7-inch, Vinyl record
