In an in-depth interview with Lawrence Pugliese at the Moonshine Theatre, Scranton, during the 2005 Ashfest, Andy Powell was asked about "Blowin' Free." He said it was one of the very first songs they ever wrote, about 1971. Although he didn't comment on its inspiration, he remembered where it was written, at the Whisky A Go-Go on Sunset Boulevard.
By "they" he meant himself and Wishbone Ash as it was then, because by the time of this interview, he was the only remaining original member, having clocked up over 35 years with the band, (although the original bass player and vocalist Martin Turner was still performing as Martin Turner's Wishbone Ash).
