Question: Is the English hard rock band that Wolfmother covered at the UK Music Hall of Fame still active? Passage:After its success in Australia, Wolfmother was later released internationally in early 2006 on 24 April in the UK, where it reached number 25 on the UK Albums Chart, and on 2 May in the US, where it reached number 22 on the Billboard 200. A number of singles were released from the album, including "Woman" which reached number 34 in Australia, number 31 on the UK Singles Chart, and number 7 on the US Billboard Mainstream Rock chart. The song later won the Grammy Award for Best Hard Rock Performance at the 49th Annual Grammy Awards, the nomination for which Heskett had previously described as "an honour". The final single from the album, "Joker & the Thief", later reached the top ten in Australia. The subsequent worldwide tour included appearances at festivals such as Fuji Rock in Tokyo, Japan, the inaugural Virgin Festival, and Reading and Leeds Festivals in the UK. On 14 November 2006, the band performed a cover version of "Communication Breakdown" by English hard rock band Led Zeppelin as a tribute to the band for their induction into the UK Music Hall of Fame.

question:
Question: What man was the lead guitarist for the shortest amount of times? Passage:The Yardbirds are an English blues rock band from London. Formed in May 1963, the group originally included lead vocalist Keith Relf, lead guitarist Anthony "Top" Topham, rhythm guitarist Chris Dreja, bassist Paul Samwell-Smith and drummer Jim McCarty. In October, Topham was replaced by Eric Clapton. He remained until 13 March 1965, when he left due to creative disagreements. Clapton recommended Jimmy Page to replace him, but he declined and Jeff Beck took over. Page later joined on bass the following June, after Samwell-Smith abruptly quit; Dreja later took over the role, allowing Page to join Beck on guitar. This lineup was short-lived, however, as Beck left in November 1966. The group continued as a four-piece until July 1968, when Relf and McCarty left due to creative differences, primarily with Page. Dreja initially remained, but by August Page formed a new group with vocalist Robert Plant, bassist John Paul Jones and drummer John Bonham, who later renamed themselves Led Zeppelin.
