2. Delbert McClinton. The Lubbock-born, Fort Worth-raised master of Texas roadhouse R&B, back on the new-release racks with the fine Acquired Taste, played harmonica on Bruce Channel's 1962 hit "Hey Baby" and accompanied Channel on the subsequent UK tour, where he met John Lennon. Accounts differ as to how much harmonica instruction McClinton actually gave the fledgling Beatle, as Lennon already knew how to play the instrument, but according to WikiAnswers.com, the Texan gave him this pointer: "Just blow, son. You're good at that." But listen to "Hey Baby" and "Love Me Do" back-to-back and it's pretty clear that something rubbed off. 3. Billy Preston. Though he grew up in Los Angeles, prolific pianist and keyboardist Preston did spend the first year of his life in Houston, which by local music calculus makes him a Houstonian for life. After befriending the group while on a UK tour with Little Richard's band, Preston played on the sessions for the Beatles' final two albums, Abbey Road and Let It Be (which was recorded first). The Beatles held Preston - who went on to play on several Rolling Stones albums including Sticky Fingers, Exile on Main Street and Tattoo You, Fastball's The Harsh Light of Day (that's his piano on "You're an Ocean") and Johnny Cash's swan song American IV: The Man Comes Around - in such high esteem they released the "Get Back" single as "The Beatles with Billy Preston." 4. The Coliseum. Houston wasn't the Beatles' first time in Texas - they played Dallas' Memorial Coliseum on September 18, 1964 - but they played twice as much here, with afternoon and evening shows at the Sam Houston Coliseum on August 19, 1965. (The setlist was the same at both shows, however, including "Help!," "Can't Buy Me Love" and opener "Twist and Shout.") In The Complete Beatles Chronicles, Mark Lewisohn reports that the Fab Four pulled down a cool $85,000 for the two shows at the 12,000-capacity Coliseum - tickets were all of $5. In Houston, Lewisohn adds, was "Beatlemania at possibly its most acute level yet witnessed"; bootleg recordings of the Coliseum show are easily accessible online. Ringo reportedly was a big Lightnin' Hopkins fan, and according to this review of his All-Starr Band's August 1995 Arena Theatre concert (featuring Billy Preston on keys), once considered moving to the Bayou City. 5. Roky Erickson and "Rocky Raccoon": A popular myth in Texas psych circles is that the bouncy White Album song is based on the troubled Thirteenth Floor Elevators frontman. It's not, but even former Elevators drummer Danny Thomas - who later played on Houstonian Johnny Nash's hits "Stir It Up" and "I Can See Clearly Now" - thought it was, and said so in a 2001 interview with the Texas Psychedelic Rock blog. The most widely circulated story concerning "Rocky's" origins is that it's Paul McCartney's parody of Bob Dylan's Western-themed John Wesley Harding album. Thomas says Dylan and Elevators electric jug player Tommy Hall had several mutual friends, and that part of Harding itself is based on Elevators songs. Thomas replaced original Elevators drummer John Ike Walton in 1967, and also admitted "psychedelic drugs were the cornerstone of our existence" in an earlier Texas Psych interview, so there's really no telling.
