Sinatra was one of the most popular singers of the 20th century. He sold more than 150 million records worldwide, and had 39 Top 10 singles on the Billboard Hot 100 chart. He also won numerous awards, including an Academy Award, a Golden Globe Award, and a Grammy Award.
The Who, on the other hand, was a British rock band that was formed in 1964. They were one of the most successful rock bands of the 1960s and 1970s, with hits including "My Generation," "Baba O'Riley," and "Won't Get Fooled Again." They have sold more than 100 million records worldwide.
While The Who was a very successful band, their popularity did not quite match that of Frank Sinatra. Sinatra was a global superstar, with fans all over the world. The Who, on the other hand, were primarily popular in the United Kingdom and the United States.
