The lyrics “People let me tell you about my best friend” are from the song “My Best Friend” by the pop group Queen. The song was written by Freddie Mercury and released in 1975. Mercury wrote the song about his cat, Jerry, who he considered his best friend.
The song is a light-hearted and affectionate tribute to Mercury’s cat. In the lyrics, Mercury sings about all the ways that his cat makes him happy. He describes his cat as being “the best friend that I have ever had” and “the one who makes me laugh when I’m sad.” The song is a celebration of the special bond between humans and their pets.
