Oooh, so difficult! This is my pared-down list, in no particular order, and no going back over it because I would have added loads more!
Sometimes when we touch - Dan Hill
Follow You, Follow Me - Genesis
Three Times a Lady - Commodores
We've Got Tonight - Bob Seger and the Silver Bullet Band
Seasons in the Sun - Terry Jacks
Behind Blue Eyes - The Who
House of the Rising Sun - Animals
A Horse with No Name - America
Sweet Home Alabama - Lynyrd Skynyrd
Whiskey in the Jar - Thin Lizzie (because I bought the single for my mum thinking she would love it!!!)
Mouldy Old Dough - Lieutenant Pigeon (just too funny)
Baby I love your Way - Peter Frampton
I'll Have to say I Love You in a Song - Jim Croce
You are so Beautiful - Joe Cocker
That's only a fraction of my real list! I have to cringeingly admit I used to cry myself to sleep over David Soul singing "Don't Give Up On Us"!!!! Anyone else?
