The excellent book by Michael Gray

William Samuel McTier
Born 5th. May 1903* - Thompson, Georgia
Died 19th. August 1959 - Milledgeville, Georgia

I was listening to the radio one day (in the 60s) when I heard Blues DJ, Mike Raven, say that there were only 6 copies of Blind Willie McTell's LP "Last Sessions" sold. I went into "Record Wise" in Egham (Owned by Adam Gibbs) and asked to order it. He had it in stock!
The above track is not from that album (this is recorded much earlier - 1928) but it's one of those songs that lasted into the'60s. Try to hear the great version by Taj Mahal [I've added a bit of it - see below].

Listen to the first 1 min of the Taj Mahal version here.

*Wikipedia gives the date as 1898 (when Blind Willie's mum would have been 10!) and The Big Book of Blues by Robert Santelli gives 1901 but Michael Gray (in "Hand me my travelin' shoes") gives compelling evidence that April 1903 to April 1904 is the probable time of birth and as the 5th. May is generally considered the birth date then the date given would be a fair bet.
