Ed Sheeran Concert Company Needed?

Hi, I've never been to an Ed Sheeran's concert and had not planned to. I'm suddenly interested to try. My few friends are busy to accompany me at such short notice. I haven't bought a ticket yet, but a friend's friend is offering to sell them for INR 4700 GA for the Sunday show. I'm thinking of buying one. It's been a long time since I went to big concert (mid 30s here) and it's daunting to go alone. So if anybody is going, can I accompany? What are some safety precautions I shall need to take? Also, is his concert worth attending on impulse like this? Please advise.
