I also know that many brown wax cylinders were also re-recorded and released under the same serial number, frequently on 2-minute black wax.
Let's begin a list of such records and their re-recordings here:
1. "In the good old summertime"
recorded by William Redmond on Edison 8118
re-recorded by Billy Murray
2. "The Belle of Kentucky"
recorded by the Edison Concert Band on Edison 8101
re-recorded by the Edison Military Band
