I've seen Iron Maiden 11 times over the years. Have you been to one of their shows?
Yes I have actually! They're such a good English heavy metal band. I love the bassist Steve Harris. Do you have a favorite song?
How can I just pick one song when everyone is amazing. Do you happen to know when they formed? 
Yes, the formed in 1975. My favorite some is the "Number of the Beast". It's also the name of their 1982 album. 
I did not realize they had been around so long. That is a great song. Do you happen to remember the name if the lead singer? 
Yeah! Well, they've actually changed singers over the years but my favorite is Bruce Dickinson. He returned in 1999 and they gained a lot of popularity after that.
Bruce is actually from my home town of Worksop, United Kingdom. I think Paul Di'Anno is better.
Really? Yeah, Paul Di'Anno was with them from 1978 to 1981. He was their first vocalist, and definitely brought a unique sound to the group. 
His voice added something that has not been matched. 
Yes I agree. Do you like the album "The Book of Souls" that was released in September 2015? It was pretty successful.
