Janis Joplin laments that people didn't "get down" during her European tour; Michael Thomas discusses music criticism; improv comedy troupe The Committee performs.

The Jefferson Airplane perform "Somebody to Love" with David Crosby as well as the politically charged anthems "Volunteers" and "We Can Be Together."

When Janis Joplin returned to the show nearly a year after her previous visit, she again came with a new band.

Sly and the Family Stone perform their #1 hit "Thank You (Falletinme Be Mice Elf Again)" followed by an interview that can best be described as odd.

Janis Joplin's final appearance on the show came just two months before her death. Joplin performs "Half Moon" and "My Baby."

Stevie Wonder performs "Signed, Sealed, Delivered I'm Yours" and "Never Dreamed You'd Leave In Summer."
