Question: It was this day in Rock History in 1973, this guy went to No.1 on the US singles chart with his first of two US chart toppers as a solo artist. Who was it and what was the song?

Answer: It was Ringo Starr with ‘Photograph’. Written by Starr and George Harrison, the promotional film shot for the single showed Starr walking around his new house at the time, which had been previously the home of John Lennon and Yoko Ono, (and where the ‘Imagine’ promo film was shot).
