Veteran rockers the Doobie Brothers have been added to the honour roll at the Music Business Association's upcoming luncheon after they were named the 2015 recipients of the Chairman Award in recognition of their career success. They join singer Martina MCBride, who will be feted at the May (15) bash in Nashville, Tennessee for her charity endeavours by officials at the non-profit Music Biz, which aims to advance and promote music commerce.
