"Richard Seff’s career in the theatre represents active participation as agent, producing associate, librettist, and, ultimately, as a skilled actor … In fact, he was responsible for recommending me to, among others, John Kander and James and William Goldman, to take over the direction of A Family Affair in Philadelphia on its way to Broadway … It turns out he’s a fine writer as well, and this chronicle of an unusual and varied life in the theatre makes excellent and valuable reading."

Hal Prince

"Oh, what a journey we’ve had. I thank Richard Seff for helping mold the life that I am still enjoying today. To live it again, through his own words, fills my heart."

Chita Rivera

"He is a clever old sausage — far more interesting to write from his perspective than from a grander vantage point — far more revealing and very redolent of the profession and its various joys, tribulations, and humiliations. Well done!"

Emma Thompson

"A very interesting look at our business from an angle most people never are aware of …"

Alan Alda

"For years, Richard Seff has been one of the wittiest raconteurs on the Rialto but a pleasure known only to the cognoscenti. Now he has gone public with a biographical reminiscence brimming with anecdota, insight, and intelligence. Bravo!"

Stefan Kanfer, Author of "Ball Of Fire"

"I know from experience as a dramatist I can often set things in motion offstage as well as on. Over the years, during productions, people have fallen in love, got engaged, fallen out of love, resolved to divorce, miscarried, gone into labour, and even on one occasion dropped dead in mid-scene. After reading Richard’s fascinating, graphic account of the backstage machinations which went on during the Broadway production of The Norman Conquests, I can now add ‘and started a civil war’."

Sir Alan Ayckbourn

"An entertaining and informative love letter to the theatre during one of its golden periods from someone who was there, and ‘saw it all’."

John Kander

"I loved the sly, wickedly funny and sardonic observations that were as pertinent to the human race at large as to that idiosyncratic subset, Show People. They made me fall in love with the business all over again. Supporting Player is a terrific read. And a classic one."

Patrick Pacheco, On Stage

"How wonderful to have Richard Seff’s memories along with his unquestionable passion for the American musical and the people who made them great. It was the best of times, and he was there!"

Linda Lavin

"Without Kander and Ebb there would be no Martin Richards, Producer, because their Chicago opened the world of musical theatre to me, and without Richard Seff there would have been no Chicago for he introduced Kander and Ebb to me. He has captured this period in Broadway’s history and made it page-turningly readable."

Martin Richards, Producers’ Circle

"This funny and fascinating book should be of interest to everyone who enjoys the theatre, and wants to know more of its inner workings and backstage shenanigans."

Stephen Sultan, President, Dramatists Play Service

"Richard Seff was there from the 1940s on, putting collaborators together, making the deals, consoling those who had written failures, and toasting the ones who triumphed. Until a time-machine comes along, Supporting Player admirably fills the niche. This is a delightful, and useful, memoir."

Peter Filichia, The Star-Ledger

"Dick Seff, actor, agent, playwright, librettist! Now his memoir comes along, filled with wonderful anecdotes about theatre folk and his experiences in dealing with them. It’s a must-read for all theatre buffs."

Price Berkley, Theatrical Index

"He captures the true spirit of what it takes to make Theatre for the serious historian as well as the devotee. It’s a must read."

Charles Van Nostrand, President, Samuel French
