Classic rock musician/band

Looking for a small local cover band/musician (classic rock & oldies) for a celebration of life at a local park Pavillion in Hamilton for Aug 16. We just want some background music to compliment the informal gathering. A guitar and singer would be absolutely perfect but open to suggestions. Our dad was big into the music scene, he was 68 so that era of 60s 70s 80s, he always supported local talent, wrote articles for arts and entertainment, so thinking a little live music would be nicer than a speaker.
