Who sings the song and/or the name of the song with the lyrics "tell me if you want me to"

This search (http://www.google.co.uk/search?hl=en&q=%22tell+me+if+you+want+me+to%22+lyrics&btnG=Search&meta=) suggests that it's either "Groove Theory - Tell Me" or "RJ Helton - Tell Me".

I think it's probably Groove Theory, because the RJ Helton lyric is "Tell me if you want me to go".
