70s stuff always goes down well at weddings-Detroit Spinners (I'll be around?) , Ojays, Delfonics, Harold Melvin, David Ruffin, Heatwave.....that's my collection down to a tee
At my wedding we had lots of folks come down and play what they wanted (was quite funny seeing my mum approach Tony Jackson and Paul Havakin to ask for some Westlife....) and it was great to be able to have exactly what you wanted played rather than listen to usual wedding poo!
