In May 1971, just prior to the release of the "Byrdmaniax" album, the Byrds undertook a sell-out tour of England and Europe, which included a performance at the Royal Albert Hall in London that was released for the first time in 2008 as "Live at Royal Albert Hall 1971". The British and European press were unanimous in their praise of the Byrds' live performances during the tour, reinforcing their reputation as a formidable live act during this period. Over the course of the tour, the band chose to expand their ranks, with roadie Jimmi Seiter joining the group on stage to provide additional percussion as an unofficial member. Seiter would continue to sit in with the Byrds during their live performances until August 1971, when he decided to leave the group's employ.
