Lithosphere-Asthenosphere boundary found to become deeper under older crust, thus supporting the suggestion that the discontinuity is closely interrelated to the LAB. Beneath oceanic crust, the LAB ranges anywhere from 50 to 140 km in depth except at mid-ocean ridges where the LAB is no deeper than the depth of the new crust being created. Seismic evidence shows that oceanic plates do thicken with age. This would suggest that the Lithosphere-Asthenosphere boundary underneath oceanic lithosphere also deepens with plate age. Data from ocean seismometers indicate a sharp age-dependent LAB beneath the Pacific and Philippine plates and has been interpreted as evidence for
Booker T. & the M.G.'s to give each other three months to finish up all of their individual projects. They would then devote three years to what would be renamed "Booker T. Jones & the Memphis Group". Nine days later (October 1), Al Jackson, the man Cropper would remember as "the greatest drummer to ever walk the earth", was murdered in his home. The remaining three members and drummer Willie Hall (a session musician who had played on many Stax hits, such as Isaac Hayes's "Theme from "Shaft"") regrouped under their old name, Booker T. & the M.G.'s, and recorded the album "Universal Language" for
