STEVEN TYLER PLAYS HOME DEPOT! 1/26

From TMZ.COM this morning ... Steven Tyler treated a bunch of shoppers at a Home Depot to an impromptu concert this weekend -- by singing two of Aerosmith's biggest hits a cappella over the store's loudspeaker. Tyler randomly picked up the microphone on Saturday and belted out snippets of "Dude Looks Like a Lady" and "I Don't Want to Miss a Thing" for all the Home Depot shoppers to enjoy. Tyler then took a hit from a helium machine and kept singing Bee Gees style while signing autographs for anyone who asked.
