I don't know, but I really noticed it throughout the Vertigo tour. I remember he used to move around a little in the early 80s, and he did that strange Adam jig during JT, just kind of moving back and forth- check out the outro of WOWY from R&H. However, he didn't do more than that on JT, Lovetown, became stationary around Zoo TV, only thing interesting was his attire on popmart, and I agree about elevation. Edge commented on it in an interview as well, saying Adam has really become a performer on this tour. I guess we could specualte- he was one of the biggest on the idea that the bomb had some songs that really were a kick back to their early days, maybe that had something to do with how he got into the shows. Also, maybe he saw how well Bono and Edge interacted on the ramps during elevation and thought he would give it a try himself. Or, more likely as we all know, it is just Adam being Adam!! He has always been a cool, yet quirky character for sure. Either way, I like it, really gives him a more prominent role in the band and puts his bass playing where it should be- right in the spotlight. I know people dump on him alot as a bassist, but where would Streets, Bad, WOWY, Gloria, COBL, Vertigo, SBS, Bullet, Lemon, all of AB and countless other U2 classics past and present be without the bass lines? People say he can not play-- I think if he could not play the critics and the record industry would have figured that out around 1980! Not all of his lines are easy either, it takes ability, he wrote the WOWY bass.
