Did Three Dog Night Destroy The Grass Roots?

I mentioned last week that The Grass Roots were put together in the mid-`60's by Dunhill records to put across the music of Sloan&Barri and others. They were tremenously successful at doing that, but then in late `68 or `69 Dunhill signed another band to do exactly the same thing. They were Three Dog Night. Three Dog Night had the gimmick of three lead singers who didn't play instruments on stage. In a sense, they were more like the Supremes than like a standard rock band. Now, at times the Grass Roots had three lead singer types, but those guys always played instruments on stage. Not Three Dog Night; Cory Welles, Chuck Negron, and Danny Hutton would just stand three abreast and croon. In any event there are only so many good songs to go around at one time, and we can guess just by the relative # of hits The Grass Roots had once Three Dog Night was signed, that they were no longer getting dibs on top songs that Dunhill was getting. I was always more of a Grass Roots Fan, but here's what Three Dog Night was doing with some of the best songs Dunhill was getting. BTW, I think only Cory Welles could have cut it with The Roots. http://www.youtube.com/watch?v=h2HH2Py4l_w
