I miss the practice of giving a rock band a name with three words, and then referring to it with three letters.

Bands like B.O.C., E.L.O., and E.L.P. will be recognized throughout time by their abbreviations. Not every three-word band made it to abbreviation notoriety. T.D.N. never really caught on.

Like so many trends, I think it was a reflection of Elvis. He was always T.C.B.
