Easy piano songs for singalong

[HexBramble]

I play the piano - learnt as a child and have played by ear as an adult.

I'm expected to tinkle the ivories at work for an informal staff party next week and am meant to chose songs that are singalongs - and I haven't a clue! So far, I have mastered Delilha and that's it! Help!

Here is a list from one web site, but look on Google for more.

Saw Burt Bacarach from Glastonbury recently, and was amazed to realize just how excellent songs he had done!
