We had asked the question earlier about the gentleman operating the "sound mixer?" in front of the JHS Pop Singers in Photo # 849. That was answered by Angela Kable and Patti Odor as Mr. C. seen above( we believe he was also known as Sonny). Patti says she operated a similar device to regulate Microphone output for the JHS   Jazz Singers a decade earlier(Where are those photos, Patti?). Angela also provided the name of the drummer in photo # 850. Thanks for the help guys, but now we still need the names of those singers in 1984 in Photo # 851 and those in the following two frames from a 1985 show!!!
