At least seven people were killed and at least 71 were injured, Governor Alexander Bogomaz said.
Mr Beard says he became "hooked" on the star's rock music, after first hearing it in 1976.He said he found the music "resonates" because of "the story in the songs - his truthfulness, the power, the rock and roll".
Along with his wife Eileen, he watched all of Springsteen's three gigs in Manchester last month.And that's on top of about 30 concerts across North America – including in Nashville and Memphis – plus many more in Europe.Mr Beard says he has been a big music fan since the age of 10, when he would listen to the BBC radio show Pick of the Pops with his mother.
He admired The Beatles and US singer Roy Orbison but admits to initially being "turned off by the hype" around New Jersey singer-songwriter Springsteen, who first released an album in 1973.However a friend encouraged him to listen to the songs Born to Run and Thunder Road in 1976, and Mr Beard recalls he "bought all three albums the next day".
Mr Beard first saw Springsteen perform at Wembley in 1981 and has since travelled with his wife to watch his concerts in the US, Canada and France.
He says that, although Eileen was a music fan when they married in 1978, "she wasn't that bothered" about the singer until seeing him perform the song Point Blank at a gig and it was "like a light went on".In a post on social media later on Sunday, the Russian defence ministry confirmed that airbases in the country's five regions were attack.
It claimed that "all attacks were repelled" on military airbases in the Ivanovo, Ryazan and Amur regions. The latter base was not mentioned by the SBU sources.In the Murmansk and Irkutsk regions, "several aircraft caught fire" after drones were launched from nearby areas, the ministry said.
It said all the blazes were extinguished and there were no casualties. "Some of the participants in the terrorist attacks have been detained," it added.Meanwhile, the Ukrainian authorities say 472 drones and seven ballistic and cruise missiles were involved in a wave of attacks on Ukraine last night.
