I love The Rolling Stones! Have you heard of them?
Yes and I love them as well! They are the English rock band who formed in London in 1962.
Wow, they've been around for a long time! Are they still around today?
I believe they do concerts every now and then. Though they are not all still alive anymore sadly. For instance, Ian Stewart passed away in 1985. Though he was removed from the official line-up in 1963. 
Oh no. The remaining members must be very old now! What were their most popular songs?
Oh man, there are so many! Back in 1965 they became very popular in the United States with hits like Time Is On My Side. 
I think I've heard that one! Do they play any other genres other than rock?
They've been known for songs in different genres, namely Blues and Blues Rock to name a couple.
