To say the crowds at the David Archuleta concerts in Idaho last week were, well, a bit unusual would be an understatement.

Half the fun was just watching concertgoers interact with each other.

The teenager from Utah — runner-up in Season 7 of "American Idol" — brought out a most eclectic crowd.

I've attended my fair share of concerts, from N*Sync to My Chemical Romance, but I've never seen a crowd quite like this.

Perhaps the group of young women from a local LDS Church ward was to be expected at the Boise concert, but the group of college students dancing and drinking was a surprise.

I never thought I would see two women in their 40s have a catfight in front of hundreds of people, but that happened when one wanted to take the other's spot in the crowd.

There was yelling, screaming, pushing, shoving and threats of further violence.

I also never thought two women in their 70s would cut in front of me while waiting in line for a concert.

For the most part, the teenagers were better behaved than the adults. Archuleta made grown women act like teenagers.

People ages 4 to 70-plus were in attendance at both Archuleta concerts (Idaho Falls on Friday and Boise on Saturday). Many fans were jumping and dancing, but some could barely walk on their own and had to be helped to their seats as they hobbled along with canes.

There were fans proudly displaying their membership in online fan communities, but also fans who had only seen Archuleta on "American Idol."

There were high school students on dates and married couples escaping from the children for a night. But the biggest group in the two crowds was made up of mothers who brought their daughters — and both were equally excited to see Archuleta perform.

And it wasn't just women and girls, there were also men and boys in the crowds, too.

The Murray teen seems to have found a way to appeal to all ages.

For many, Archuleta's concerts were a family activity. Mothers, fathers, sons, daughters and even grandparents were all in attendance.

There were multiple families where the daughter, mother and grandmother came together.

And people traveled from all over to see Archuleta perform — including a contingent that travels from city to city so they can attend multiple concerts. Last weekend, some drove from Seattle. Many came from Utah. One group of fans flew to Boise from New York City for the show.

When Archuleta noticed their sign displaying how far they had traveled, he was stunned and became flustered while introducing the next song.

Maybe the crowd is a reflection of how unique Archuleta is. He put on interesting and amusing shows, complete with funky dancing and unashamed silliness — courtesy of the adults.
