Who is sampled in this 90s dance track
 

I know this dance tune from 1998 by Psychedeliasmith called "Different Strokes". I am 100% sure it samples a / several well known funk song(s) but I do not know which one. Especially at 1:55 you hear some well known brass section.

(if the first one who replies can wrap it within the youtube tag I would be very pleased. I can not do that because this is my first post)
