After (inadequate!) basics:
Code:

+-------------+---------+-------------+
| 49 49   5   | 2  6  7 | 1   8   3   |
| 36 37   367 | 8  1  4 | 9   2   5   |

+-------------+---------+-------------+
| 34 1    37  | 79 45 6 | 8   359 2   |
| 8  467  2   | 79 45 3 | 47  569 1   |
| 5  3467 9   | 1  2  8 | 347 36  46  |
+-------------+---------+-------------+
| 1  5    4   | 6  3  9 | 2   7   8   |
| 69 2    8   | 5  7  1 | 34  369 469 |
| 7  39   36  | 4  8  2 | 5   1   69  |
+-------------+---------+-------------+

Play this puzzle online at the Daily Sudoku site



And the same result from a 37 W Wing in c23.

(This reply feels a bit like deja vu!)
