The 92Y series, I’m guessing, is very similar to the Grammy Museum series, with a sit down interview, and quite possibly Lu on guitar for a few songs.
John Mellencamp has done two of these sit downs at 92Y. I went to the first one, where David Fricke from the Rolling Stone sat down and asked JM the questions. The theater space, as I recall, is padded seating in a lecture like hall. I really enjoyed the evening.
