It's Boston University Night at the Pops (meaning that at some point they'll perform the university's Alma Mater and the sports "Fight Song"). The BSO performance detail page tells us
Join Broadway stars Jodi Benson, Doug LaBrecque, and Donna McKechnie as they pay tribute to the wonderful talents of one of the greatest contributors to music over the last century, Marvin Hamlisch. As composer, Hamlisch won virtually every major award: three Oscars, four Grammys, four Emmys, a Tony and three Golden Globes. On Broadway, he wrote the music for the long-running show, A Chorus Line and They're Playing Our Song. His more than forty motion picture scores include his Oscarwinning score and song for The Way We Were and his adaptation of Scott Joplin's music for The Sting. This memorable concert will feature music from his vast array of timeless music.
I was at the Hamlisch tribute show on Tuesday, and it was good. Since the theme of the Pops season is "Lights, Camera, Action!" there's lots of movie music in it. So I think you'll enjoy it if you like that sort of thing. Pre-concert show on Classical New England is at 7:00, concert at 8:00, rebroadcast/webstream May 26 at 1:00.
Tomorrow, May 19, at 1:00, they retransmit last week's "Fantasia" program.
