I'm not too familiar with David Essex's Rock On. Tell me something about the song.
It has a unique bass line. The lyrics speak to me. It is a classic rock song from 1973 
I'm a big fan of unique basslines. What's your second favorite David Essex song?
Hold Me Close is another one I enjoy. But it is not as good. Do you like classic rock?
Yeah, I do. The '70s were the best era for that genre. Is David Essex the singer or does he play an instrument?
He was a singer/song writer only. I am sure I saw him playing guitar a couple of times, but it might just be my old mind playing tricks. He was well known for his voice.
I'll make sure to stream his 'All The Fun Of The Fair' album later. Are there any live performances of his that I should check out?
He has a few that are on Youtube, but he reached the UK top 40 with 19 songs, so a lot of his life performances are on tour in that part of the world. Most of them do not have great quality because they are either very old, or newer with people filming with cell phones.
His Legends tour was in 2019. Do you think he'll tour again and play "Rock On"?
I don't know if he will. He is 73 years old now! He might decide after all of his hard work to just relax a bit haha.
