I interviewed Adrian Henri in 1995 for the The Argotist magazine, which was the print predecessor of the The Argotist Online. Only some of the interview was used in the magazine.
The original audio cassette of the interview has now been converted to MP3 format and is now on YouTube. It is in four parts. It covers a range of topics: performance poetry, the practicalities of performance poetry gigging, written poetry and spoken poetry, poetry set to music, Bob Dylan as poet, and many other things.
