Funny thing......I couldn't remember the name of the song, but I remembered the group right away. My Dad seemed to have a passion for anyone using a number in their group name.....Four Tops, Four Preps, etc. and the "brother" named groups, ie. the Mills Brothers. Odd though that I don't recall anything by the Brothers Four.
And Bill......on 5 string? You definitely need to put that on a share file for us to listen to!!!
