When Taylor Swift calls and asks if you would like to perform with her at a sold out show you don't say "I'll think about it", you say "What time should I be there?" Taylor was preparing for her 3rd sold out show in Newark, New Jersey when she phoned Pat Monahan, lead singer of Train, and asked him to join her on stage. Check out the result.

It was a knockout performance of Train's hit "Drive By".

According to Taste of Country it was a performance to remember.

Monahan appeared on stage, dressed in all black, descending the staircase, singing the first verse of the lyrics, with the Swift crowd singing in unison, nearly drowning him out. Swift was having a grand old time, rocking out, dancing like a maniac and shaking her thing while Monahan sang his verse and chorus. In that sense, she was no different than her fans — loving, enjoying and geeking out to a song and an artist she loves.
