The Doors made their international television debut in May 1967, recording a version of "The End" for the Canadian Broadcasting Corporation (CBC) at O'Keefe Centre in Toronto. But after its initial broadcasts, the performance remained unreleased except in bootleg form until the release of The Doors Soundstage Performances DVD in 2002.
On September 17, 1967, the Doors gave a memorable performance of "Light My Fire" on The Ed Sullivan Show. According to Ray Manzarek, network executives asked that the word "higher" be removed. The group appeared to acquiesce, but performed the song in its original form, because either they had never intended to comply with the request or Jim Morrison was nervous and forgot to make the change (Manzarek has given conflicting accounts). Either way, "higher" was sung out on national television, and the show's host, Ed Sullivan, canceled another six shows that had been planned. After the program's producer told the band they would never play on the show again, Jim Morrison reportedly replied: "Hey man. We just did the Sullivan Show."
On December 24, the Doors performed "Light My Fire" and "Moonlight Drive" live for The Jonathan Winters Show. Their performance was taped for later broadcast. From December 26 to 28, the group played at the Winterland Ballroom in San Francisco; during one set the band stopped performing to watch themselves on The Jonathan Winters Show on a TV set wheeled onto the stage.
The Doors spent several weeks in Sunset Studios in Los Angeles recording their second album, Strange Days, experimenting with the new technology, notably the Moog synthesizer they now had available. The commercial success of Strange Days was middling, peaking at number three on the Billboard album chart but quickly dropping, along with a series of underperforming singles. The chorus from the album's single "People Are Strange" inspired the name of the 2009 documentary of the Doors, When You're Strange.
