Welcome everyone,

I'm overwhelmed with 70's and 80's music and know hundreds of bands, radio broadcasts and DJ's, but lately I've found on YT
this remix:


From about 6:30 to 8:20 there is a disco-song I can't identify. Shazzam and soundhound spitted out one big nothing, and searching by heard lyrics also turned out to be uneffective. Does anybody know what is the band and name of this song?
