A young David Bowie—soon after changing his name—interviewed at the height of his Anthony Newley fixation and a performance of “Over the Wall We Go” a seldom heard track (that I happen to love).

YouTube poster, “Eclipse1501” writes:

In London in 1966 at the Marquee Club David Bowie did a Sunday afternoon show, The Bowie Showboat, from April 10th to June 12th. At the second Bowie Showboat concert he met his soon to be manager, Ken Pitt. This recording is almost 45 years old so forgive the period live sound quality but enjoy a young entertainer. There is an audio break in the middle but stick with it!

The break occurs at 2:08 and resumes at 3:10.
