My feeling on Van Halen is lukewarm. They put out some decent stuff, but I don't believe they are in the same league as all the greats - Led Zeppelin, Jimi Hendrix, The Beatles, The Who, Pink Floyd, etc., etc. Many of the mid 80's/90's bands are better too - Pearl Jam, Soundgarden, U2, Red Hot Chili Peppers, Metallica, to name a few.
Live? Never seen them live
Album? Women And Children First
Song? Don't have one
Member? Don't have one
