Well...the typical concert dress for the Hardcore Al Fan includes:
1. Al related T shirt. The older the concert tour, the more cool points you have.
2. Hawaiian print shirt over this.
3. Probably wearing Vans.
Other things I have noticed among our more obvious members (and I include myself in this, but I'm not saying which ones

)
1. They are probably sitting in the first 10 rows of the concert hall
2. They are probably singing along word for word, and probably also at least lip synching the video segments
3. They might be wearing a costume of some sort
4. Star Wars memorobilia (especially Yoda) is popular
5. They are probably hanging out by the buses post show. For hours.
6. They have a tendency toward admiring other funny/quirky musical acts--They Might Be Giants, the Arrogant Worms, Moxy Fruvous, etc. Almost everyone I know who plays the accordion is an Al fan.
Ultimate hardcore?
I can direct you to two folks here who are famous among fans....Fred and Elvis. Sorry guys.
What brings these guys so far into the limelight among fans?
1. They usually see multiple shows on a given tour. Generally this is in the double digits (I'm definitely not saying this is a bad way to spend time...I'm there too)
2. They have pretty extensive collections of AL memorbilia
3. They are both also known for the Al related body art...Dave/Elvis has the band, and Fred/Denise had the artwork from the cover of Peter and the Wolf.
I personally have found that Al fans are generally very nice and fun to be around. They are not like everyone else....they tend to be more open minded about music and interested in all sorts of other unusual things. They tend to be pretty smart, and funny, and love to find people who appreciate the subtlties of "Dare to be Stupid" too.
