Ketch----I don't recall you ever doing a Top 10 tribute to one of the greatest rock/blues bands of all time, namely The Allman Brothers Band. What that band was doing in the studio & live starting in 69/70 was astonishing. Few bands, if any {and that includes AC/DC}, have been able to touch them in concert---before, during or since.
If Jessica, Ramblin Man, Blue Sky, and the 2 masterpieces---In Memory of Elizabeth Reed, and Whipping Post--- doesn't blow you out of your chair, then its time for a medical check-up.
You're right. I've never done them.
Is it time?
