I haven't seen this before..Mullin obit from 1999. It says that the first commercial recording issued from tape was "Songs by Merv Griffin" in 1946. http://www.aes.org/aeshc/docs/jaes.obit/JAES_V47_9_PG776.pdf This also gives Merv the claim for the first tape-mastered album. http://en.wikipedia.org/wiki/Merv_Griffin dl
