Dravanaksha : There was a discussion about the Radha-Damodar kirtans that we were having on campuses and on the streets. At that time we had many instruments. We had a harmonium, an esaraj, which was like a violin, an ektar, and we had an instrument that had strings that we'd play with little hammers. Adi-Keshava said that the people were attracted to the party because of the instruments, but Prabhupada didn't seem to take that very seriously. Prabhupada said that we should just use khols and kartals. Adi-Keshava said, "But Vishnujana said?" Prabhupada cut him off. Prabhupada said, "Who is Vishnujana? I am your spiritual master." Prabhupada also said that we shouldn't play the harmonium during the aratis. Previously, Baradraj and others played harmonium during the aratis, but after they heard that they stopped. Prabhupada didn't want just expert musicians, he wanted devotees. So for a while, the Radha-Damodar party went back to mridanga and kartals in the public kirtans, and eventually added a couple of instruments here and there? I heard with Prabhupada's permission, but I don't know for sure.
