The first project to be billed as a "rock opera" remains some of The Who's most popular work, other than 'Who's Next', and continues it's wild ride through rock history with upteen re-releases, tributes and stage shows.  You certainly know the familiar chorus lines of  "sure played a mean pinball" and "see me, feel me" which helped make the album so big, but do you recall how the album started?  The brilliant, mostly instrumental 'Overture' set the mood for the album and is a pleasure to play again on today's Vault.  Out of town?  Listen live on-line.
