As most garage-music bands, the Nightcrawlers was a one-hit wonder. That hit came in 1967 with “Little Black Egg.” The band and their hit were a flash in the pan. By the time the song charted, the band had broken up. The 45 is worth no more than $20.00 while the album, “Little Black Egg,” released on Kapp Records in 1967, is worth up to $250.00 today.
