You can hear the Celtic heartbeat all over Europe and America, from Bing Crosby to Jack White, from the Smiths to My Bloody Valentine, from House of Pain to Marky Mark and the Funky Bunch.

But bringing people together is what music has always done best.

Davy Jones was the grooviest of the Monkees, which makes him one of the grooviest pop stars who ever existed. He was the best dancer in the Monkees, the Cute One, the one with the coy English accent, the bowl-cut boy-child who shook those cherry-red maracas and always got the girl. He was also the guy who stole David Bowie's original name.

On 'Idol,' Steven Tyler will be sitting at a table with two other judges, and part of his job will be keeping his yap zipped while they talk. This makes no sense at all, since Tyler has zero yap-zipping skills.

When I started out as a music journalist, at the end of the 1980s, it was generally assumed that we were living through the lamest music era the world would ever see. But those were also the years when hip-hop exploded, beatbox disco soared, indie rock took off, and new wave invented a language of teen angst.

It was bewildering and humbling to keep discovering how many brave things people can fail to talk themselves out of doing.

Hometown Aerosmith fans are different from other Aerosmith fans, and that mainly has to do with Joe Perry. It's tough to overstate his strange grip on the local psyche. Tyler is a star who belongs to the whole world, but Perry, that dude belongs to Boston.
