Not really a "hits" type of band as they saw little to no airplay either via radio or MTV and still have sold over 100 million albums. If interested in a CD that has a lot of good intro songs, try "Best of the Beast" from 1996.
I will, thank you. I have always wanted to see them live. I like Bruce Dickenson (i think), he has a commercial pilot license, he even flew their tour plane (still might).
