Question: Which band that Yokam released cover songs from has more members, The Clash or Queen? Passage:Johnny Cash once cited Yoakam as his favorite country singer. Chris Isaak called him as good a songwriter as ever put a pen to paper. Time dubbed him "A Renaissance Man" and Vanity Fair declared that "Yoakam strides the divide between rock's lust and country's lament." Along with his bluegrass and honky-tonk roots, he has written or covered many Elvis Presley-style rockabilly songs, including his covers of Queen's "Crazy Little Thing Called Love" in 1999 and Presley's "Suspicious Minds" in 1992. He recorded a cover of The Clash's "Train in Vain" in 1997, a cover of the Grateful Dead song "Truckin'", as well as Cheap Trick's "I Want You to Want Me". He has never been associated only with country music; on many early tours, he played with hardcore punk bands like Hüsker Dü, and played many shows around Los Angeles with roots/punk/rock & roll acts. His middle-period-to-later records saw him branching out to different styles, covering rock & roll, punk, 1960's, blues-based "boogie" like ZZ Top, and writing more adventurous songs like "A Thousand Miles From Nowhere". In 2003, he provided background vocals on Warren Zevon's last album The Wind.

Question: What band were Dio and Iommi in together before Heaven & Hell? Passage:Though his parents were from Cortland, New York, Dio was born in Portsmouth, New Hampshire, where his family resided for his father's service in the U.S. Army during World War II; they soon returned to Cortland. Dio's music career began there in 1957 as part of the Vegas Kings (later Ronnie and the Rumblers). In 1967, he formed the rock band Elf, which became a regular opening act for Deep Purple. In 1975, Deep Purple guitarist Ritchie Blackmore founded the band Rainbow and hired Dio to be his lead singer where the band released three studio albums. Dio quickly emerged as one of heavy rock's pre-eminent vocalists. In 1979, Dio joined Black Sabbath as lead singer. He appeared on three studio albums with the band which met with success: Heaven & Hell (1980) and Mob Rules (1981) and Dehumanizer (1992). In 1982, he left the band to pursue a solo career with two albums certified platinum by RIAA. In 2006, he founded the band Heaven & Hell with ex-bandmate Tony Iommi. Dio was diagnosed with stomach cancer in 2009, from which he died the following year.
