Dorothy and I went to see Ken Walker at the Madison Meadows Retirement Residence this afternoon. Retirees crowded into the Front Hall at 1:30 to hear him spin his Time-Life CD Series-- top hits from across the decades-- and wait for everyone to shout out the name of the tune and the artist. Ken keeps the performance going with his friendly interactive conversation and "DJ-patter", playing songs on nothing but a CD player using a paper-based index and a big ampflier on a cart. It works well as he catches the after-lunch crowed at Madison who enjoy an after-lunch concert.
