In 1969, Slappy and Skippy go out to Woodstock, NY, to get some rest, but find themselves in the middle of the biggest music and arts festival ever assembled. Features the "Who's on Stage" routine, patterned after the classic Abbott & Costello routine "Who's on First".
Dr. Scratchensniff has a cameo lasting only four frames in the escape scene to the magic bus. This would later be refrenced in the "Please Please Please Get a Life Foundation" cartoon.
The musical artists referenced/shown in this short include The Who, Yes, The Band, Jimi Hendrix, the Grateful Dead, Simon & Garfunkel ("The Sound of Silence"), Janis Joplin, Buffalo Springfield ("For What It's Worth"), John Lennon, Jefferson Airplane, Country Joe, Melanie, and Joe Cocker.
Jimi Hendrix played a guitar-heavy rendition of "The Star-Spangled Banner" at Woodstock. Slappy closes the cartoon with a polka version.
In the cartoon, Joe Cocker sings an altered version of "With a Little Help from My Friends" and Melanie sings a version of "Brand New Key".
Skippy says The Band is performing later, although it would be more accurate to say "tomorrow" since The Who performed day two and The Band performed day three.
The Who didn't play on stage at Woodstock during the afternoon. They played at 5:00 in the morning, just before sunrise.
Earlier in their career, The Who would destroy their instruments as the finale of large shows. They had stopped doing this by the time they played Woodstock, however, and bass guitarist John Entwistle almost never participated in the destruction.
Woodstock occurred in 1969, but Skippy has a Hair poster in his bedroom. Hair did not open on Broadway until 1970. This would also later be referenced in the "Please Please Please Get a Life Foundation" cartoon.
Melanie is singing a version of "Brand New Key," a song which would not come out until 1971.
The Who's frontman is given a Liverpool accent when they were actually from London.
The Warners return to the water tower via a lasso from Wakko's gag bag. When Ralph pulls the rope, a horse falls on him. The Warners just shrug and go back into the tower.
