disco/funk/soul RFI

ok so ill start with the admission that im a follower not a leader musically, and that in this case i am following Skream ,who did a great set on rinse recently where he just played early 80s soul funk and disco.
every tune, albethey well worn, was a banger pretty much.
so what do i neeed to look for to follow these sort of tunes?

patrice rushen - forget me nots
mary jane girls - all night long
george benson - give me the night
gwen mcrae - keep the fire burning/all this love that im giving
....

any more tunes in that vein would be appreciated. theres a thread of just... well, funk (with a lower case "f") that links these, even if they predate the electonic sounds in disco they retain a similar feel, very punch basslines moving away from the lushness/symphonic stuff.
