Oasis? Definitely Nappy Brown.
I doubt if you'll find the vynil version,but \it's on "The Golden Age Of American Rock'n'Roll vol 4" which can be purchased from ACE Records catalogue.
Hi all. i wrote the TV ad. It's an old blues track by Nappy Brown. I had the theme of 'the little things in life' and chose that track over a different track with the same title by Dusty Springfield.
