Deli-that link you put up was a new one on me-not where the 4 of top 8 albums quote came from-but yer right-its obviously a fan oriented thing. Different link than the one I posted a bit ago for the guy who wants "proof"--I spose you could check RIAA stats too but I aint quite that compulsive. Point was all those songs listed for '58 above and MY point was 4 albums at once in the Billboard top 10 at once. To me thats influence more than sales and it all started with that first red album and swept the country and started the folk music era here which the progenitors didn't do. As for the UK I have no idea who was big there or if they had a folk boom like in the U.S. Lonnie Donnegan? Buskers? Dunno.
