He played 'Heard it in a Love Song' early in the set. It was excellent and as expected everyone sang along. I have seen videos of him singing 'Can't You See' acoustically. He does both songs justice and I've heard him refer to the Marshall Tucker Band as the best band in the world. King is from Greenville which is near where the Marshall Tucker Band was from.
My wife met Marshall Tucker years ago. Most of the time when she tells people that they tell her that there was no Marshall Tucker in the band.
My wife used to read books on a local radio station in South Carolina for the Commission for the Blind. When she went to the yearly banquet for the Commission she noticed that she was seated next to Marshall Tucker. He was the blind man that the band was named after.
On a different note, I've been streaming (Qobuz) some of Marcus King's albums on my primary system and his recordings sound good, particularly Mood Swings and Darling Blue. They do not seem overcompressed like most new stuff these days.
I'm planning on buying some of his CDs. I hope they will not be over compressed.
