Fifty-four years have passed since classic rock legends Pink Floyd embarked on their very first North American Tour. The outing was part of their 1968 World Tour where they visited Europe before heading to the States.

1968 was a pivotal year for PF, as their former lead singer Syd Barrett left the band officially in April, and stopped playing with them as early as January. The tour kicked off in Europe in February and David Gilmour became the main frontman, dropping most of Barrett's songs from the setlist.

On July 8th, PF headed to North America for their first tour. It kicked off in Chicago at the short-lived Electric Theater. We don't have the setlist details but other setlists from the tour tell us that PF was still performing two Barrett-composed tracks: "Interstellar Overdrive" and "Astronomy Domine."

According to our setlist archives, they also would weave in "A Saucerful of Secrets," "Set Controls for the Heart of the Sun," "Flaming," "Matilda Mother," "Let There Be More Light," "Remember a Day," "Careful with That Axe, Eugene," "Pow R. Toc H.," and "Paintbox" - All very early era PF songs you'd rarely hear in their later years with the exception of "Astronomy Domine."

Another rare performance they would do on the tour was an early, shorter version of "A Saucerful of Secrets," called "The Massed Gadgets of Hercules." This was also the year they included a large gong as part of the shows on the tour.

The North American leg lasted over a month, wrapping up on August 24th in Torrance, California.

While Pink Floyd haven't performed together in over a decade, David Gilmour and Roger Waters continue to perform PF songs as solo artists.
