On stage, I have seen Lane in A Funny Thing, Guys and Dolls, The Producers, It's Only a Play, Butley, The Front Page, The Nance, November, The Man Who Came to Dinner, The Odd Couple, Laughter on the 23rd Floor, Love Valor Compassion, and Gary. Even given that I HATED Gary, I have never seen him give a lee-than-wonderful performance,
I did not see the Angels in America revival, nor was I able to see Waiting for Godot, as neither worked with my out-of-towner calendar.
With that background, the decision is very easy for me. I think Lane gave the greatest musical performance I have ever seen by a actor, with Christopher Plummer in Cyrano being second. I know that people like to diss The Producers now, but they need to remember that they are dissing it because they feel it is not as good as they thought because Nathan Lane left.
My second favorite Lane performance: The Nance or The Man Who Came to Dinner, two wildly different roles.
