Thomas Rundle Reilly MBE (August 21, 1919 – September 25, 2000) was a Canadian-born harmonica player, predominantly based in England.
Born in Guelph, Ontario, he studied violin at eight and began playing harmonica at aged eleven as a member of his father's band.
He began parallel careers as a concert soloist and recitalist, a popular BBC radio and TV performer, and a studio musician-composer.
He performed music for the soundtracks of many US and European films and television series, including British comedy The Navy Lark (1959) and the TV theme tune for Dixon of Dock Green.
He and James Moody have recorded many musical scores for the harmonica under the pen names "Dwight Barker" and "Max Martin".
