Giving their second performance of William Schuman's "Free Song" in two weeks, 55 men from the Harvard Glee Club will travel down to Carnegle Hall tomorrow for an afternoon concert with the Boston Symphony under the direction of Serge Koussevitsky.

In their second weekend trip, the Glee Club will sing with Pembroke College today and entertains the Harvard Club of New York on Sunday. Helping the men hit the high notes in the Carnegle concert will be the Radcliffe Choral Society.

Tibbetts is Narrator

The "Free Song," the world premiere of which was given in Symphony Hall last Saturday evening, is a musical adaptation of some of Walt Whitman's poetry. Paul D. Tibbetts '45 will take the role of male narrator.

This concert will be the third that the club has scheduled with the Boston Symphony Orchestra, in addition to the performances with the "Pops" musicians.
