Song

Dad and I have both heard a song, but we have know idea who sings it or what it's called. I've checked all the lyrics search sites, etc...I can't find it. I last heard it on the radio in Ontario...I think it might be Canadian. The only words we know are "lazy river", sung by a background singer that has the worst voice ever heard. It's not the Grateful Dead song...anybody know what song it is?

Could do with more to go on...

Sorry...could be "down the lazy river" or "up the lazy river"...I dunno.
