It is suggested that many of the high-velocity, low surface gravity, early-type stars are Old Disk Population objects in the same evolutionary phase as the hot UV-bright stars in globular clusters. The bimodal Gaussian fits to the peculiar radial velocity distribution result in Gaussian distribution values of 13 km/s and 28 km/s which are typical of extreme Population I objects and of the Old Disk Population. An analysis of the kinematics of a sample of OB stars indicates solar motion and mean peculiar velocities typical of Population I objects; it is concluded that up to 39 percent of the O-type and 11 percent of the B-type stars may be Old Disk Population objects, referred to as Disk-UV-bright stars.
