B.A. Rolfe was known as a "high note specialist" and would play solos that usually included a "flutter tongue" technique that he worked out to go up to concert D and Eb. Edison "What Good is Good Morning" #51,750L contains a fine example.
In the early 1940's, my trumpet teacher, Frank Graf, was the cornet soloist with Herbert A. Clarke's Long Beach Municipal Band which B.A. Rolfe conducted as Clarke had retired by then. According to Frank both Rolfe and Clarke could still "play up a storm" and B.A. could still hit the high notes. Frank stated that playing under Rolfe was his greatest musical experience and B.A. was a "fine gentleman".
