"The Skyliners are an American doo-wop group from Pittsburgh fronted by Jimmy Beaumont. The original lineup also included Wally Lester, Jack Taylor, Joe Verscharen, and Janet Vogel. While this quintet constituted the formal group of vocalists, they were backed by a variety of Pittsburgh musicians including Joe Dalu, a drummer from Pittsburgh's Manchester neighborhood who also played with local favorites Ray and The Furys (COED Label, 1959). The Skyliners were best known for their 1958 hit "Since I Don't Have You." Popular covers by Trini Lopez, Chuck Jackson, Don McLean, Guns N' Roses, The Brian Setzer Orchestra, Ronnie Milsap, and Buckaroo Banzai have helped keep the song in the public consciousness. They also hit the Top 40 with "This I Swear" and "Pennies From Heaven." Other classics include "It Happened Today"(1959), "Close Your Eyes" (1961), and "Comes Love" (1962). The original group dissolved in 1963 but reunited 11 years later (without Jack Taylor) for what would become their last charted record, "Where Have They Gone?""
"Beaumont still performs with The Skyliners in their current lineup of Nick Pociask, Dick Muse, and Donna Groom (whose husband, Mark Groom, has been the group's drummer/conductor for more than 25 years). Two of the original members have died; Janet Vogel (suicide) in 1980 and Joe Verscharen of cancer in 2007."
