Among the previously reported artists who will perform at the show, dubbed “A Celebration of the Music of Jimmy Webb: The Cake and the Rain,” are Art Garfunkel, Judy Collins, Johnny Rivers, ex-Fifth Dimension members Marilyn McCoo and Billy Davis Jr., Glen Campbell‘s daughter Ashley and Webb himself. Douglas will deliver a spoken-word performance.

Proceeds from the concert will be donated to the Alzheimer’s Association in honor of Glen Campbell, who suffers from Alzheimer’s and for whom Webb wrote such hits as “Wichita Lineman,” “Galveston” and “By the Time I Get to Phoenix.” The event will come on the heels of the April 18 publication of a new memoir by Webb called The Cake and the Rain.

Other acts on the tribute concert’s bill include country artists Toby Keith and Dwight Yoakam, and veteran pop star Amy Grant.

The show is being presented by City Winery, whose founder, New York entrepreneur Michael Dorf, organizes the “Music Of” series of annual tribute concerts held at Carnegie Hall. To purchase tickets and find out more details about the show, visit MusicOf.org.
