Well, we were pretty well immersed in musical interludes in Khartoum, resulting in daughter Caroline, and Beau, deciding to live and work there.
Here's a selection of Youtubes. Including a clip I uncovered featuring the two of them.

'Meroe' sung by Rasha Sheikh Eldin. Featuring the pyramids at Meroe.

Friday afternoon prayers at the Hamed el Nil mosque in Omdurman (across the river from Khartoum).

Some Sudanese hip hop at Papa Costa restaurant in Khartoum, where Beau and Huila played to a full house.

A view of Khartoum at election time and hip hop at Papa Costa's.

Music and politics in Sudan - and memories of Khartoum pavements and the tea-and-zalabya (doughnut) stalls.

What a surprise to find this...... No music, but plenty of birdsong. And at 0:35 appears Caroline and Beau chatting to a local visitor..... Didn't know there was a camera around!
(Beau's bike just visible behind. And McCrankpin's armchair appears at left of picture at the end, tent just behind)

Not very Sudanese. German band 'Elegant Jazz Trio' perform at the Sailing Club a while before we arrived.

Abdel Gadir Salim (western Sudan) sings 'Bissarma'.

As we approach the Ethiopian border here's a Sudanese song, 'Zanoba', performed by Ethiopian singers and dancers.
