Adapted from the 1925 stage hit The Grand Duchess and the Waiter (previously filmed in 1926), Here is My Heart has been subtly reshaped into a Bing Crosby vehicle. Der Bingle plays J. Paul Jones, a wealthy radio crooner (what a stretch!) who falls in love with icy Russian princess Alexandra (Kitty Carlisle). Unable to get close to her through diplomatic channels, Jones disguises himself as a waiter and gains access to her lavish suite. When it turns out that Alexandra and her relatives are broke and in danger of being evicted, our hero secretly buys the entire hotel to preserve his beloved's regal reputation. Ultimately of course the Princess falls in love with him -- and only then does she discover that the humble hotel waiter has been her benefactor all along. The songs include the enduring favorites "Love is Just Around the Corner" and "It's June in January."
