A talk on an invited topic sponsored by the Centre for Robert Burns Studies, University of Glasgow, and held at the Robert Burns Birthplace Museum, Alloway, on January 12, 2019. Among topics discussed are variant texts of the song "Yestreen I had a pint o wine" [The gowden Locks of Anna], and the date, background and manuscript sources for "Fragment: Esopus to Maria." The talk is not fully referenced, and only selected powerpoint slides are included, but fuller references will be provided if and when topics are written up for formal publication. A section of the talk about the long-lost first newspaper publication of the disputed short poem "Delia: An Ode" has been removed [April 2019], as its discussion has now superseded by subsequent research, to be published separately.
