Junior Senior Whatever

What the hell does it matter that Junior is straight and Senior is gay, and why does it seem impossible to read anything ever written about the band without this fact mentioned? Is it meant to be special in some way that a gay person and a straight person are friends, and work together? For all I care, Junior could be the president of Hitler Youth and Senior could be a one-legged homosexual Jewish gypsy, and this still wouldn’t be enough to compensate for the fact that their music is shit.
