I wrote something here about Lennon and my ride home tonight. I'll add to this list.
John Lennon: Instant Karma
(actually, you could probably do an entire sefira just with beatles songs, if you wanted to ... I'm tired, and will sleep now, but I will come back to this tomorrow or later this week.)
Put It There - Paul McCartney
Let Me Roll It - Paul McCartney (that has nothing to do with sefirah, I just like it)
... further development on the sefirah theme ...
Time to put the spiritual money where the mouth is. Engaging in extra acts of VLK during sefirah. One a day. (two, now, 'cause sefirah's been going for a while) I'm up for the challenge.
