Violinist Yehudi Menuhin will turn 75 soon and plans to visit his 95-year-old mother in California. The former child prodigy, who now lives in London, will play and conduct at an April 22 concert at Royal Festival Hall, with Vladimir Ashkenazy assisting.

Menuhin holds dual citizenship in America and Britain, where he was knighted. His lively interests include maintaining connections with music schools named for him in England and Switzerland, doing commercials for Rolex watches, and trying to prevent publication of a biography, "Menuhin, a Family Portrait," by Tony Palmer, which he considers unfavorable.- CHARLES MOULTON, familiar to Utahns from his "Nine-Ball Precision Hand-Passing" for the Repertory Dance Theatre, made another dance with balls, "Panoranagram," for the Joffrey Ballet's current season in Los Angeles. Moulton is the winner of the 1989 Dorothy B. Chandler Performing Arts Award.
