Is this the earliest Nick Cave interview?

This is fascinating: An early—1978—interview with Nick Cave and Rowland S. Howard back when the group that would eventually gain infamy as the Birthday Party were still known as the Boys Next Door. Cave would have been 20 years of age here and 18-year-old Howard hadn’t even been in the group very long at all at that point.
