What are the rock bands from the 70s & 80s that आप wish आप could have seen that no longer has the lead singer now that they did then?

for me वैन, वान Halen when David Lee Roth was in the band I believe they were the best. Journey when Steve Perry was lead singer the band hasn't had nearly the success it has had since his departure. My सूची can go on & on but these are the probably the चोटी, शीर्ष two =)
