When a tribute band sell out the same arenas their subjects did, you know they're onto something and that is just the case with Killer Queen, a bunch of British superfans who've made celebrating their idols into an art form. Led by charismatic Freddie Mercury-look-and-soundalike Patrick Meyers, what started as a one-night thing has now spanned over 25 years and been welcomed the world over!

Two of the twentieth Century's most revered and beloved piano men are represented in this unmissable tribute from Mike Santoro and Kenny Metcalf. Each taking turns onstage, these talented performers channel Joel and John respectively in an authentic and electrifying showcase, giving a two-for-one line up made in heaven!

Going strong since 1940, this gospel and country quartet (composed of Joe Bonsall, Duane Allen, William Lee Golden, Richard Sterban) were inducted into the Country Music Hall of Fame in 2015. Celebrated for songs such as 'Elvira', 'Bobbie Sue', 'Touch a Hand, and Make a Friend', 'Gonna Take a Lot of River' and 'American Made', the group continually tour and perform, even collaborating with newer artists.

10-man acapella group Straight No Chaser, who found fame on Youtube after forming at Indiana University, continually dazzle audiences with their renditions of pop classic and modern chart hits with highlights "Let It Go", and Pharrell Williams' "Happy" catapulting the group to mainstream success. This fall, they're back on the road again, celebrating the holiday season on the Top Shelf tour!

The Irish all-male wonder from producer Sharon Browne, and legendary songwriter/composer Phil Coulter, performs an eclectic mix of songs ranging from the traditional to the contemporary, with some international hits and original material in between. Boasting boy-band good looks and impeccable harmonies, the group delivers traditional Celtic songs and contemporary pop classics as only they know how.
