In 2004, when Paul McCartney performed "Yesterday" at the Glastonbury Music Festival, he was enjoying a resurgence in his solo career. This performance was part of his "Summer Live '04" tour, which showcased his new material and classic hits. Prior to this event, McCartney released the album "Driving Rain" in late 2001, which included a mix of new songs and reflected his experiences following the death of his first wife, Linda. The Glastonbury performance marked a significant moment for McCartney, as it underscored his enduring appeal and ability to connect with live audiences—he became the oldest headliner of the festival at that time. "Yesterday," one of The Beatles' most iconic songs, remains a testament to his long-lasting influence in music, as he continues to perform it decades after its original release.
