The first was inspired / somewhat copied from a beer commercial. The second reminds me of a children's show for some reason. The third was made because Dm7 and G7 go so well together.
As you can probably hear, I'm no good with endings.
The latter evolved into the former by playing it over and over. Except for the endings, they use an identical progression. Dedicated to a friend who is finding it tough to get inspired.
Started as a jam between me and a friend. I couldn't get the tune out of my head, so I refined it a bit, re-recorded both parts myself, and did a bit of a mixing job.
