Unbeknownst to me, legendary King Tubby's Sound System opened for The Wailers at National Arena on September 26, 1975.  According to journalist Carl Gayle of Black Music news, Tubby played until 6 a.m. the following morning, reclaiming his title of 'King Tubby,' which had recently been challenged by several other sound systems.

This show was previously dated as 'August 29, 1975, however, based on Gayle's announcement, it is clear that the National Arena show occurred on September 26, 1975.
