“These days I seem to think a lot about the things that I forgot to do for you, and all the times I had a chance to.”

These are the opening lyrics to “These Days,” penned by Jackson Browne and made famous by Nico in 1967.

About a decade later, Southern rock icon Gregg Allman would record the song for his solo album Laid Back, which includes a host of tributes and two solo versions of Allman Brothers hits.
