According to the Internet source given below, Nat Gonella was an English, jazz trumpeter, bandleader and vocalist.
He played in several bands during the 1920s and 1930s, including Archie Pitt's Busby Boy's Band, Bob Bryden's Louisville Band, Billy Cotton's Band, and worked with musicians Roy Fox and Lew Stone, before forming his own band, The Georgians, in 1935.
Personal remarks:
I had the pleasure of experiencing him live somewhere around Portsmouth in the early 1960s. Some 40 years later I was at a jazz club in London when I mentioned to the trumpeter of the group I was listening to that I had seen Nat all those years ago. He became animated when telling me that he too had performed him. I thereupon requested that he would play Wildcat Blues (1923) (my absolute favourite). Unfortunately, although willing, his bandleader declined.
