Everything about that album is legendary. Although I think the Isle of Wight show was even better, especially "Young Man Blues".
I saw The Who in LA at the Forum in 1980 on the 3rd night of 5 sold out shows. Daltrey’s vocal performance was one of the greatest I ever witnessed from a rock band, including having seen Bono/U2 live in 1992 at Anaheim Stadium.
Speaking of form, here is a pic of Roger and Robert from a few years ago...you can tell who took care of himself (no pun intended).
