Rock journalist Steve Rosen has a YouTube channel with lots of long interviews with rock stars
I just posted one of them, his 1977 Jimmy Page interview, in this thread about Classic Rock republishing his 2005 story about covering Led Zeppelin's '77 tour: https://www.democraticunderground.com/1034145486 .
The channel is at https://youtube.com/@SteveRosenInterviews .
