Editing Princeton Triangle Club (section)

===The Lyon era===
''Spree de Corps'' (1955–56) marked the debut of [[Milton Lyon]] as Triangle director. From 1955 until his death forty years later, Lyon would direct all but a handful of Triangle's original productions.

Student apathy toward extracurricular activities began to affect Triangle toward the end of the 1950s. At a meeting in October 1958, the board noted a very small turnout for the previous month's auditions. It was decided that more on-campus publicity would help, and as part of this effort Triangle Junior was formed, a group of seven club members who performed favorite Triangle songs at various receptions and functions. Over the following years, this small group would undergo periodic name changes, being known as ''Triangle Ding!'' and ''Triangle Bit Parts'' before returning to ''Ding!'', as it is called today.

With the gradual elimination of passenger trains in the late 1950s, the club began touring by bus. Early in 1960, there was a proposal to produce a motion picture on the Triangle Club, but a Hollywood writers' strike and possible heavy expenses brought an end to this publicity idea. However, Triangle did embark on its first European tour that summer; the club performed ''Breakfast in Bedlam'' (1959–60) at French and German bases of the American army. ''Tour de Farce'' (1961–62) became perhaps the most widely toured show: performances in Pasadena and San Francisco marked the first time the show had been seen live on both coasts, and then troupe members again went to Europe that summer to perform at U.S. Army bases.

''Funny Side Up'' (1963–64) was billed as the 75th anniversary show in spite of the fact that number seventy was ''Tour de Farce'', produced only two years earlier. ''Funny Side Up'' did not have a smooth start: the writers were slow to produce material, and the trustees even considered the possibility that there would be no show. Because of the diamond jubilee, twenty-one songs from earlier shows were made a part of the program. The tour of ''Funny Side Up'' included several southern stops, and the [[Birmingham, Alabama]], visit became problematic when Triangle was booked into a segregated theatre. After some strongly worded letters from board members, it was determined that the performance would either be cancelled or moved to a non-segregated house.
