Breakdown (studio rehearsal 1976) - Tom Petty & the HBs (‘Going Home’ documentary)

Early on in the 'Going Home' documentary (1993), a very young Tom Petty & the Heartbreakers perform "Breakdown" in the recording studio. The audio here is different from the one on the soundtrack to the 'Runnin' Down a Dream' documentary (2007). Because the video from the first chorus in this video appears in the documentary, however, I have blacked out that portion of the video.
In the end of the video you can hear TP in the background talk about the band being formed in the recording studio and the centrality of Mike Campbell's production and songwriting abilities to the band's sound. Denny Cordell also chimes in at the end to talk about the rise of disco in relation to rock and roll music.
Enjoy!
