I left Grant’s Tomb in mid afternoon and was walking south on Broadway when I saw this at 102nd Street. It’s an electronic billboard that the city uses to let the public know about subway changes and things like that. Actually Elvis recorded two live albums this day, though one of them was not released until twenty years after he died. The King played four shows at Madison Square Garden during his June 1972 stint, the first time he had performed in New York City since the late 1950s. The shows on Saturday the 10th ended up as An Afternoon in the Garden and Elvis As Recorded at Madison Square Garden. The latter was rushed into production and released just one week after the concert, and the afternoon show was released in 1997.
