Ten Years After was formed in England in 1967 with Alvin Lee as their controversial leader. Two years later they rocked Woodstock with their exciting rendition of “I’m Going Home.” They had little success on the singles charts but their albums sold well. Their biggest hit came in 1971 with “I’d Love to Change the World,” which is worth no more than $10.00. Their 1968 album, “Undead,” on Deram Records, featuring George Gershwin’s “Summertime” and Woody Herman’s “Woodchoppers Ball,” is worth up to $125.00. Add another $100.00 if cover has a sticker promoting “I’m Going Home.”
