Where have we heard this interview before?

This site's section on Radio Show and Promotional Records has a description of the most interesting Chuck Berry records which were not available for public sale. This includes the so-called Radio Show albums which are LPs (later CDs) containing pre-produced radio shows to be broadcast by radio stations nation-wide. Some of these albums contain interviews or even music not available anywhere else.
I recently received another of these radio albums containing five segments of 5 to 7 minutes each to be broadcast as House of Blues Breaks on CBS stations. The segment for Thursday, 21 April 1994 concentrates on Louis Jordan but holds an interview segment by Chuck Berry related to Jordan.
Berry says:

They say that's a Chuck Berry song because it goes 'da-da-bi-da-bi-da-bi-du-a-da-bi-du-a'. Well, the first time I heard that was one of Carl Hogan's riffs in Louis Jordan's band. We have T-Bone Walker - I love T-Bone Walker and his blues. So you put a little Carl Hogan, a little T-Bone Walker, and a little Charlie Christian, the guitarist in Tommy Dorsey's band, together. Look what a span of people that you will please. And that's what I did in Johnny B. Goode, in Roll Over Beethoven. And making it simple is an important fact, I think, that resulted in a lot of the artists understanding, being able to play my music. If you can call it my music. But there's nothing new under the sun.

This does sound very well-known. We have heard Berry tell this in multiple interviews before. However, I checked the remaining radio station albums and did not find this specific segment. Do you remember where we have heard this specific interview segment before? Let me know.
