I don’t remember Black Sabbath or Billy Joel either. Perhaps the previous commentor confused Alice Cooper and Black Sabbath. Rod Stewart? Maybe the faces, how ’bout that set from Nitzinger sat. afternoon!

the event was actually damn good, not bad as you seem to remember.
B.B. King, Jonathan Edwards, Cactus, Brownsville Station, Nitzinger, The Mahavishnu Orchestra, Herbie Mann, E.L.P., J. Geils and Elephant’s Memory w/ the ever present roumor that John and Oko were on their way. John and Oko didn’t happen but they did send a taped message played that Easter morning.
The Allman Brothers Band was the closing act saturday night and Alice Cooper closed Sunday, or really monday pre-dawn after an inspired set by Emerson Lake and Palmer.
E.L.P. had hours of trouble getting the Moog to work in the tropical heat and mist but when they came on at 4:00 a.m., in a coconut grove, they just gave one of the performances of their career.
Elephants Memory opened Monday morning, ’bout 11:00a.m. but I had to leave . I had to be back at High School in San Juan. Damn shame as they say Monday was the real highlight.

more like 11:00 p.m., the brothers, I believe, closed the show that night following B.B. King

I can add “Whipping Post”, “You Don’t Love Me” and “Statesboro Blues” to the set list

The AWTNM from this show is on the Dreams box set.

Billy Joel actually did play the Mar Y Sol Festival. He was touring behind his “Cold Spring Harbor” LP, and gained some recognition from Rolling Stone magazine as well as Columbia Records, the company that signed him a year later.

This was Billy’s Mar Y Sol setlist:

TRAVELLIN’ PRAYER
JOSEPHINE
CAPTAIN JACK
TOMORROW IS TODAY
THE LETTER
JUMPING JACK FLASH
BALLAD OF BILLY THE KID

Granted this was a LONG time ago,but I don’t remember Black Sabbath or Billy Joel being there I do remember great sets from J Geils John McClaughlin Alice Cooper and of course the great set by the Allmans I still have my ticket stub and the album that was released

This was another attempt to recapture the Woodstock spirit in the early ’70s by staging a rock festival. Despite some good acts such as the Allmans, ELP, Black Sabbath, Rod Stewart, and the up-and-coming Billy Joel (!), the event was marre
