I would go. My DH bought me tickets to Michael Buble just before we found out we were pregnant and then when we found out we were having twins I wasn't even sure I would make it that far in the pregnancy as it was when I was 36 weeks pregnant. Low and behold I made it to the concert (I asked my Ob if I should go or not in case the noise would harm the babies and she said to go)

So at 36 weeks with twins (huge so everybody was staring at me like I was a freak show lol ) I went to the concert. The twins danced around the whole time, having a ball and they love it in the car if I play them some Michael Buble. When they are whinging in the car I can put his CD on and they are instantly quiet!!!
