Entertainment We present live musical entertainment from a rotating roster of performers every Monday and Wednesday from 12:45. The cost is $10 per person, and includes lunch served at midday, but if you arrive after lunch the cost for entertainment only is $7 per person. Transport is available on Monday and Wednesday for members at minimal cost. A variety of entertainers play at COA, and attendees are encouraged to dance. At times of the year when music is not normally permitted (the Omer and the Three Weeks) we may present a speaker or slide show during these periods, but usually we get a special dispensation from a rabbi to continue playing music because it is so good for the brain and body, and can be considered rehabilitation and maintenance of mental and physical health.
