This was the first Elton John album I owned (on vinyl), and there was no doubt about upgrading to CD/digital.  A very solid offering from what I consider his peak period.  From Madman, to Honky Chateau, into Don't Shoot Me, culminating with Goodbye Yellow Brick.  All excellent, all worth having.  Looking back over 35+ years, I'd rate this as the least excellent of that quartet, but all are worthy.  But Madman (which peaked at only #8) laid the groundwork for the subsequent string of #1 albums.
