performance lasting ten more minutes". Phil Freeman wrote of this "doubling effect", stating "Miles's two solos fit together perfectly, creating a feel similar to that of New Orleans jazz, with two trumpets weaving intricate, complementary lines around each other". In Milestones: The Music and Times of Miles Davis, Chambers writes of Davis's segment and the complex production of "Go Ahead John", "In spite of the gimmickry, the blues segment manages to state some old verities in a new context, and state them powerfully. Most jazz listeners can hope that someday Go Ahead John will be unscrambled and re-presented to them as, among other things, an unhurried blues by Davis accompanied only by Holland". Down Beat critic John Ephland interprets the recording to be "Miles' most obvious allusion to the Godfather of Soul, James Brown", adding that "Conjuring up images of Brown's 'I Can't Stand Myself' and 'I Got the Feelin',' from '67 and '68, respectively, 'Go Ahead John' shuffles, swirls, gets down and runs rampant, with some very creative editing, courtesy of producer Teo Macero". Allmusic editor Thom Jurek writes of the recording, "There is no piano. What's most interesting about this date is how it prefigures what would become 'Right Off' from Jack Johnson. It doesn't have the same fire, nor does it manage to sustain itself for the duration, but there are some truly wonderful sections in the piece". In Running the Voodoo Down: The Electric Music of Miles Davis, Phil Freeman calls the recording "one of the best things Miles and Macero created during the 1970s", writing that "It's a singular achievement in production, one that presents Miles in a different light than anything else in his catalog".

It ultimately reached number 179 on the chart and number six on Billboards Top Jazz LPs chart. According to Todd S. Jenkins of All About Jazz, "The long, ever-droning, darkly exotic electric music, and in fact the very idea of just four songs taking up four full sides of an album, was not too appealing to critics or the general market at a time when short, sharp disco tunes were beginning to chart like wildfire. So Big Fun received generally weak reviews". In a positive review, Billboard
