The Wailers (with Bob Marley, Peter Tosh and Bunny Wailer) Catch A Fire LP

Man is this like the greatest album ever or what? I could listen to this all day! I am doing so in fact.. Just got through the original US zippo lighter cover and I'm now listening to the Jamaican LP.... Aston Familyman Barrett is just awesome on this... he's mixed in really nice with that extremely fat bass...This record first came out as a "Wailers" record but I guess was subsequently released as "Bob Marley and the Wailers".. the question of course is this: was the zippo case the only issue under "The Wailers" and it sold its as rumoured 20,000 run, then Burnin' came out under "Wailers" and only then was Catch a fire released with the Bob Marley smokin' a joint cover and credited to "Bob Marley and the Wailers" or is there an issue with the Bob Marley smoking a joint but credited to "The Wailers"? Why the change from "The Wailers" to "Bob Marley and the Wailers" and when did this change happen? Also the original zippo cover LP of Catch A Fire features a different mix/slightly longer mix of "Baby we've got a date" apparently... Either way whatever the history this is just a wonderful album. the issue is if it peaked at around Billboard 150 how many copies sold say in the first year? Where all the copies sold the first year the lighter copy?
