Money's bassline wins it for me.
Fat Old Sun, Atom Heart Mother, If, The Nile Song, Julia Dream, ARNOLD LAYNE!!! SEE EMILY PLAY, Candy and a Currant Bun, Careful with that Axe Eugene, Childhood's End, Free Four, etc...
'High Hopes' is my favourite, i'm mentally adding that to your list ;)
Otherwise, i chose:
Hey You, Bike(had to), Have a Cigar, Goodbye Blue Sky.. and quite a few more.
Oh, also, i can't find 'Take It Back' which is a favourite of mine.
They just have too many songs to list, really ;)
I've heard of them, but i dont listen to them...
