Glen Park (park)

The nightclub was notable for featuring the bands Wilmer & the Dukes and Raven (formerly Tony Galla and the Rising Sons) on a weekly basis, which helped launch their careers.

In addition, national recording acts such as Junior Walker & the All Stars, The Butterfield Blues Band, Sly and the Family Stone, Ike & Tina Turner, The Bob Seger System, The Esquires, Gary Puckett & the Union Gap, Wilson Pickett, Wayne Cochran & the CC Riders, and Arthur Conley also played this famous nightclub.

Altman, his son-in-law Dave Goldstein and grandson Steve Goldstein had hosted many famous entertainers at the Glen Casino over the years, including Sammy Davis Jr., Frank Sinatra Jr., Jayne Mansfield, Dick Shawn, Joey Bishop, Jerry Vale, The Three Stooges, and the Mills Brothers.

In 1966, Kevin Elliott, a local promoter, sold Harry Altman the idea to convert the nightclub into a rock 'n roll venue.

This local group featuring Tony Galla on vocals, Jim Calire on piano, John Weitz lead guitar, Tommy Calandra on bass guitar, Gary Mallaber on drums, became national recording artists known as Raven managed by music executive, Marty Angelo.
