Wow. I haven't heard that name in many years!
I would describe Wallace as an old school CO. He fashioned himself as a genteel, southern 'gentleman' - sometimes with white shoes and suit (a la Colonel Sanders). A friend once told me that in an elder's meeting he told the brothers that he wore the 'white hat' during his visit to the congregation and they we're in charge of doing 'the dirty work'...
He would refer to himself on stage as 'Brother Wallace'. And, once from the platform he stated, 'we ALL tell little white lies from time to time, don't we'....with a big grin on his face.
