This goes out to Prince Kate and Kate Middleton who're getting married today. I wish them all the best, hope they'll be happy together, and that this song sums up how they'll still feel for each other in the years ahead. "Ain't No Mountain High Enough" was written by Nickolas Ashford and Valerie Simpson for the Tamla Motown label in 1966, and became a huge hit for Marvin Gaye and Tammi Terrell the following year. The ultimate love song? I like to think so!
