Joe Long of The Four Seasons belongs in the R&R Hall of Fame

Joe Long is the tall bass player standing in front of Frankie Valli on the train tracks (He is the only only bankd member in this photo/album cover not in the Rock and Roll Hall of Fame with the Four Seasons) Why not?

Why is Joe Long the only member of The Four Seasons not in the Rock and Roll Hall of Fame? When I saw The Four Seasons in concert in 1965 all the girls where screaming for Joe and he was the "cool" one on stage. So does anyone know why he is not in the Hall of Fame with the other The Four Seasons? He was one of the coolest bass players and stage performers I've ever seen, and I've been to many, many rock shows! Anyway, just wondering why he was not inducted with Gaudio, Valli and DeVito. I believe Nick Massi was also inducted, but not really sure who he is. Its been awhile, but rock & roll and The Four Seasons fans are unsure why Joe Long is not in the rock and roll hall of fame with the other band members. Anyone know why???
