Not always easy, but found info at this site http://www.jsonline.com/

Based on listening to a portion of every Beatles track, I have identified 86 titles with Paul the featured singer.

Some are McCartney solos ("Yesterday," "Michelle," etc.), whereas others have varying degrees of harmonizing by John Lennon and George Harrison.

Seventy-one of the tracks were originally issued during their years together (1962-'70):

"All My Loving," "All Together Now," "And I Love Her," "Another Girl," "Back in the U.S.S.R.," "Birthday," "Blackbird," "Can't Buy Me Love," "Carry That Weight," "Day Tripper," "Drive My Car," "Eleanor Rigby," "Fixing a Hole," "The Fool on the Hill," "For No One," "Get Back," "Getting Better," "Golden Slumbers," "Good Day Sunshine," "Got to Get You Into My Life," "Hello Goodbye," "Helter Skelter," "Her Majesty," "Here, There and Everywhere," "Hey Jude," "Hold Me Tight," "Honey Pie," "I Saw Her Standing There," "I'll Follow the Sun," "I'm Down," "I'm Looking Through You," "I've Got A Feeling," "I've Just Seen a Face," "I Will," "Kansas City," "Lady Madonna," "Let It Be," "The Long and Winding Road," "Long Tall Sally," "Love Me Do," "Lovely Rita," "Magical Mystery Tour," "Martha My Dear," "Maxwell's Silver Hammer," "Michelle," "Mother Nature's Son," "The Night Before," "Ob-La-Di, Ob-La-Da," "Oh! Darling," "P.S. I Love You," "Paperback Writer," "Penny Lane," "Rocky Raccoon," "Sgt. Pepper's Lonely Hearts Club Band," "She Came in Through the Bathroom Window," "She Loves You," "She's a Woman," "She's Leaving Home," "Sie Liebt Dich," "A Taste of Honey," "Things We Said Today," "Till There Was You," "We Can Work It Out," "What You're Doing," "When I'm Sixty-Four," "Why Don't We Do It in the Road," "Wild Honey Pie," "Yesterday," "You Never Give Me Your Money," "You Won't See Me" and "Your Mother Should Know."

Another 15 tunes were more recently unearthed from early '60s sessions and BBC appearances and came out in the '80s and '90s:

"Besame Mucho," "Come and Get It," "Hallelujah, I Love Her So," "Hippy Hippy Shake," "Junk," "Like Dreamers Do," "Love of the Loved," "Ooh! My Soul," "Searchin'," "September in the Rain," "Step Inside Love / Los Paranoias (medley)," "Sure to Fall (in Love With You)," "Teddy Boy," "That Means a Lot" and "That's All Right (Mama)."

George's and Ringo's tracks originally issued during the group's years together (1962-'70):

George Harrison: "Blue Jay Way," "Chains," "Do You Want to Know a Secret," "Don't Bother Me," "Everybody's Trying to Be My Baby," "For You Blue," "Here Comes the Sun," "I Me Mine," "I Need You," "I Want to Tell You," "If I Needed Someone," "I'm Happy Just to Dance With You," "The Inner Light," "It's All Too Much," "Long Long Long," "Love You To," "Old Brown Shoe," "Only a Northern Song," "Piggies," "Roll Over Beethoven," "Savoy Truffle," "Something," "Taxman," "Think for Yourself," "While My Guitar Gently Weeps," "Within You Without You" and "You Like Me Too Much."

Ringo Starr: "Act Naturally," "Boys," "Don't Pass Me By," "Good Night," "Honey Don't," "I Wanna Be Your Man," "Matchbox," "Octopus's Garden," "What Goes On," "With a Little Help From My Friends" and "Yellow Submarine."

Next are their Beatles tunes unearthed later from '60s sessions and BBC appearances. All came out in the '80s and '90s:

George: "All Things Must Pass," "Crying, Waiting, Hoping," "Don't Ever Change," "Glad All Over," "I Forgot to Remember to Forget," "I Got a Woman," "I'll Be on My Way," "Not Guilty," "Nothin' Shakin'," "Shout," "So How Come (No One Loves Me)," "Take Good Care of My Baby," "The Sheik of Araby," "Three Cool Cats," "You Know What to Do," "Young Blood."

Ringo: "If You've Got Trouble."

All others sung by John.

In summary

Singing lead on 86 Beatles tracks puts McCartney well ahead of George Harrison (40) and Ringo Starr (12), but a bit behind John Lennon (103).

Not included are tunes featuring Tony Sheridan (e.g., "My Bonnie"), duo and trio harmony (e.g., "This Boy"), and instrumentals (e.g., "Flying").
