One of the nation’s longest-running celebrations of the life of the late civil rights leader, the 48th annual Martin Luther King, Jr. Memorial Breakfast (pictured) once again takes place at the Boston Convention and Exhibition Center on January 15. The public is invited to hear inspirational speeches by the region’s civic and religious leaders along with guest speakers while enjoying great food and live music. Also taking place on MLK Day, at 7 p.m., is Take My Hand: 15th Annual Dr. Martin Luther King, Jr. Tribute Concert, a special musical performance by Boston Children’s Chorus at Symphony Hall that honors the legacy of one of the 20th century’s most important figures.
