You may keep it one song as your signature song but please don't play the same old repeated song list eberywhere, coz it signfied your incapabilites , at the same time people r fed up of the same old repeated song. Actually we like you a lot but if you happen to go on playing the same old repeated song which is not your original song , how could we even watch or witness your performance, leave it about like or subscribe.
They are just cover band it seems they don't have originals of their own yet. And new songs & efforts in performance should improve, it's a paid concert not free.
