My own musical time machine is “Ferry Cross the Mersey,” by Gerry and the Pacemakers. I heard this poignant song played by a cover band at Melanie Roberts’ eighth-grade graduation party in Long Island, and I was transfixed. Eyes closed now, I can still hear every note, feel the dampness under my suit jacket and recall with wonder the girls of St. Ignatius Loyola grammar school, suddenly transformed into young ladies in party dresses and heels. We had been children together, and now we were halfway to adulthood.
