Searching for 60's, 70's band from Chicago area

While on the road with a band from Ohio, we met a band from the Chicago area in a night club in Grand Rapids, Mi......They were a trio and went by the name of Rodger or Roger......I have no last names, only first name basis.......Jimmy-Bass Guitar/Vocals, Billy-Lead Guitar/Vocals and Mark-Drums/Vocals......They were awesome.......With their permission I recorded a night live and I'm sure they would like to have the recording preserved for memories......If anyone knows their whereabouts, you may have any of them contact me via e-mail...........The club in Grand Rapids was the Canopy Lounge......This was in the late 60's to early 70's...........One other piece of info.....I know the 3 of them had just separated from a funk band......Thx...
