Has anyone else noticed that many - in fact almost all - well known 
dance callers and musicians are almost never mentioned on Wikipedia?

I was recently asked about Allan Block. A brief search showed me that 
although his daughter, Rory Block, an accomplished blues singer, has an 
entry in Wikipedia, Allan does not. Searches of Wikipedia for names like 
Bob McQuillen, Dudley Laufman, Ralph Page, and others also came up with 
nothing. Ted Sannella is the only contra caller or musician who I found 
with a Wikipedia entry. Maybe there are a few others. Should more be there?
