Okay, here we go. The Memphis Grizzlies are playing Portland this afternoon at 4 p.m. at The Pyramid in a special nationally televised game to commemorate Martin Luther King Day. The game will not only showcase the NBA stars and pioneers, but will feature a tribute to musical artists, including Isaac Hayes singing the National Anthem and a halftime show featuring Billy Rivers and the Angelic Voices. This is all followed by the first annual National Civil Rights Museum High School Basketball Invitational. Call 205-1234 for information about special packages.
