Thanks to all for mentioning resp. discussing approximately 20 various blind blues singers up to now.

Here are some other blind blues singers I've never heard of:

- Blind Bo Carter
- Blind Willie Reynolds
- Blind Roosevelt Graves

Are they known to you? Are you aware of others?

Re.: "blind piano blues singers". Because piano tuners tend to be blind and are mostly able to play this instrument I cannot understand why there aren't any blind piano blues singers to remember. (Apart from mentions and arguments above).

Last but notleast, happy birthday to Blind Mississippi Morris, Tweed.
What's his age?
