I would have treasured a tv recording of Glastonbury, but hey, it didn't happen. Remember, this is a 73 year old guy who recently lost virtually all his money, and who while he is enjoying being on the road has made no attempt to hide the fact that he needs to replace some of the lost money.
His manager not only ripped off all his money but also sold all his song rights to Sony - the rights which had hitherto underwritten his source of income. So it's possible that had Len been broadcast live on the BBC at Glasto he would have had to have paid Sony a fortune in royalty rights for the privilege of playing his own songs. Screw that.
He is not on this earth to please us. Though he does, in spades. It is not wrong for him to act in his own spiritual and economic interest. There will, I hope, be a dvd somewhere along the way. I take your point that going out live on the BBC may have enhanced his profile, but then that's some nebulous stuff compared with the possible large sum of cold hard cash he would have had to pay, gallingly, in royalty rights to his own songs. Plus, as noted, the tv audience for Glasto wasn't actually that big at the time - the football and other stuff detracted attention.
As to being in the presence of God.....well,
Relaxed and open hands extended towards others convey the message that we are merely conduits for blessing -- k’lei kodesh in the literal sense, instruments and vessels through which God’s holiness flows. When we do our work seriously and with care, when we trust in the reality of a power greater than ourselves, Divine blessings come through us, through the touch of our fingers and the deeds of our hands, into the people we serve.
This is what the Midrash [Tanhuma, Naso, 8] means when it playfully describes the outstretched hands of the Kohen [hereditary priest] by quoting a verse from Song of Songs, in which the lover furtively gazes at his beloved: “There he stands behind the wall, gazing through the window, peering through the lattice” [S of S 2:9]. When the Kohen spreads out his hands, says the Midrash, God is peering through the lattice; God is present in the spaces between his fingers.
