Terrific song.
It was originally called “Think I’ll Pack My Bags” , and was released on Rod's terrific box set "The Rod Stewart Sessions 1971-1998" in 2009. Here's a review from Rod's fan club Smiler. This is a piece of this review.
More than a third of THE ROD STEWART SESSIONS 1971-1998 chronicles the torrent of indelible recordings Stewart unleashed during the ’70s. Fittingly, the set opens with a decidedly rough take of “Maggie May,” the #1 hit from Stewart’s third solo album–Every Picture Tells A Story–that broke him as a solo artist in 1971. SESSIONS offers alternate versions of well-known hits from that era such as “Sailing,” “Tonight’s The Night (Gonna Be Alright),” “You Wear It Well,” and an acoustic version of “You’re In My Heart (The Final Acclaim).” Alongside those are rarities like the unfinished “Think I’ll Pack My Bags” (which later appeared on Ron Wood’s solo debut rewritten as “Mystifies Me”)
