What is have you seen your sister naked?

"Have You Seen Your Sister, Baby, Standing in the Shadow?" is a song by The Rolling Stones. Released in 1967, it features a distinct upbeat tempo and is noted for its horn section, which was less common in the band’s music at the time. The song deals with themes of youthful rebellion and exploration. Despite being a popular track among fans, it wasn't included on many studio albums, making it somewhat of a hidden gem in The Rolling Stones' extensive discography.
