 Teehan points out that although the Gavin Report recommended that radio stations withdraw the single from airplay , many stations did not comply with this request . In addition , Teehan notes that the radio ban was not suggested by the Gavin Report until April 29 , 1966 , almost seven weeks after the single had initially been released — ample time for it to have made its mark on the charts . Teehan has uncovered evidence showing that " Eight Miles High " was already decelerating on the national charts before the end of April 1966 . He concludes that the groundbreaking song lacked strong commercial appeal by virtue of its complexity , unique sound , and excessive length ( commercial radio stations were reluctant to play songs that were over two @-@ and @-@ a @-@ half minutes long during the mid @-@ 1960s ) , and that it suffered from uncoordinated and inefficient promotion by Columbia Records .
