In 1970, Traffic toured in support of their comeback album
John Barleycorn Must Die, with a quartet line-up of
Steve Winwood,
Chris Wood,
Jim Capaldi, and
Ric Grech. In November, the group played a series of concerts at the
Fillmore East, and recordings from these concerts were compiled into a live album, to be called
Live Traffic, consisting of "Who Knows What Tomorrow May Bring", "Glad", "Pearly Queen", "
40,000 Headmen", "
Dear Mr. Fantasy", and "
Can't Find My Way Home". This album was set for release in early 1971 but cancelled for unknown reasons, though Side A eventually appeared as bonus tracks on the 1999 reissue of
John Barleycorn Must Die. By the time of their next tour, Traffic had expanded with the additions of Dave Mason,
Jim Gordon, and
Reebop Kwaku Baah. The band only played six dates, two of which – their opening performance at Fairfield Hall, Croydon and a London benefit for
Oz – were recorded and mixed to become
Welcome to the Canteen. Mason was keen to take this version of Traffic to the United States, but Winwood was only interested in doing these six dates. Mason said, "It's Stevie's band, so it's up to him."
Welcome to the Canteen would be the last album Traffic would release under the band's North American distribution contract with
United Artists Records; their next album
The Low Spark of High Heeled Boys would be issued by
Island Records, who released Traffic's records in the U.K. and who (in late 1971) had recently established operations in North America. ==Release and reception==
