Going Out Tomorrow Night

Anyone want to guess who'll be gigging?
There are clues but no prizes, just the satisfaction of knowing you have a superior knowledge of music from the last twenty years or so. Oh, and bragging rights of course. Extra points if you can also identify the songs:

1) Still there's a light I hold before me
You're the measure of my dreams

2) There was nothing ever gained
By a wet thing called a tear

3) And as the sunset came to meet
The evening on the hill
I told you I'd always love you

and

4) If you're lonely, I will call -
If you're poorly, I will send poetry

5) Is there a flag that flies above your heart
And is my name writ there upon it?

6) Here we are in our summer years
Living on icecream and chocolate kisses

Remember: Googling the lyrics is cheating, and as there are no prizes, pretty pointless. Have fun.
