I guess I an going to give away my age, but I was 16 when this album came out. It was such a huge hit and everybody, I mean EVERYBODY, had this album, at least in my age group. Growing up in the Midwest, rock music was king and the list of debut albums by epic rock bands in the 70's was very long. An album was $5 and I had a really good paying job so I bought as many albums as I could afford in those days.
